To make a burger, grab a raw patty from the fridge, and place it on the hob. Quickly grab a burger bun and combine it with the patty once it's cooked. Hopefully you didn't burn the patty!
To serve a customer, you must first let them sit down and decide what they want. The menu is extensive, so it takes them a few seconds. Act on them to take their order.
Tables must be cleared before customers will sit at them. Clean the dirty dishes in the sink. You're fat so be careful not to eat the customers.
