theres a few tricks that were missied. When parking, o straight to the customer pick up - loading area. If anyone asks, you'll just be a sec.
Enter through the exit if you already have a good idea of what you want. Pass the casheirs and go straight to the warehouse.
If you must browse through the different sections, learn the short cuts. (I always wonder in case of a fire lots of people would die as they try to snake there way out following the blue arrows on the floor)
Other than that I like the drinking idea, I didn't know they served there.
