The system includes a countertop portion, a barrier section, and one or more trays. The countertop portion has a front side and a back side. The barrier section is coupled to a bottom side of the countertop portion along the front side of the countertop. The barrier section is configured to support the countertop portion in use. The barrier section defines one or more openings therethrough. Each tray is aligned with one of the one or more openings and slidable relative to the barrier section between a retracted position and an extended position. Each of the trays is closer to the back side of the countertop in the extended position than it is in the retracted position. Each of the trays passes at least partially through its respective opening when sliding between the retracted position and the extended position.

An expandable food cart for use in a vehicle trailer or a pick-up truck bed and a method for assembling the expandable food cart in the vehicle trailer or pick-up truck bed are described. The expandable food cart comprises a collapsible frame configured to conform with a front end cross section and a back end cross section of the vehicle trailer or pick-up truck bed. The expandable food cart further comprises an expandable shading unit having a side expanding portion and a top expanding portion. The expandable food cart further comprises a utility box located in the front end cross section between a first side of the collapsible frame and a second side of the collapsible frame. The expandable food cart further comprises collapsible shelves configured to attach to a sidewall of the vehicle trailer or pick-up truck bed. The expandable food cart further comprises an expandable work surface.

A vision-based self-checkout terminal is provided. Purchased items are placed on a base and multiple cameras take multiple images of each item placed on the base. A location for each item placed on the base is determined along with a depth and the dimensions of each item at its given location on the base. Each item's images are then cropped, and item recognition is performed for each item on that item's cropped images with that item's corresponding depth and dimension attributes. An item identifier for each item is obtained along with a corresponding price and a transaction associated with items are completed.

A bar assembly includes, in combination, a foldable counter and a pair of support legs arranged to support the counter in a table-type formation. Each support leg is configured as an open-sided, rectangular-shaped enclosure. The support legs are positioned in an upright, standing orientation to support the counter. The counter includes a set of openings, each adapted to receive a removable sink-type basin. A faucet is associated with one of the sink-type basins. A rear panel removably extends between the pair of upright support legs at a rear bar area manned by a bartender. A rear speed rail receptacle is removably attached to the rear panel. An arrangement of front panels removably extends between the pair of support legs at a front customer service bar area. One of the front panels includes a central panel section extending above the counter at its periphery, and a pair of pivotable end panel sections each hingedly attached to the central panel section. A foldable elevated shelf is disposed over the counter and supported by the end panel sections once they are pivoted into a shelf-supporting position. A water supply system uses a foot-powered pump to communicate water selectively and manually from a water-holding receptacle to the faucet via hoses. The pair of support legs define joinable half sections together forming a selectively openable and closeable case defining a storage space. In a stowage configuration, the bar assembly is disassembled, and various components are stowed in the storage space of the case, including the folded counter, the folded shelf, the rear panel, the rear speed rail receptacle, the basins, and the arrangement of front panels. One of the half sections of the case includes a set of wheels and a handle to facilitate portability and mobility.
