I work in a 3-level mall just off the Beltway (which may give you an idea of how massive and often crowded it is). In our small corridor of this shopping world, I often forget just how large Tyson's Corner Center is ("corner center" - I really hate that). Thus I am grateful to know Lora, my mall cartographer friend.
"Lora, where is the Panera?"
"Is there a bathroom there?"
...I'm a little freaked out by Mr. Toilet, to be honest...
