Do they let baby carriages in? How about wheel chairs? Cruches, walkers, shopping carts? Larks?
The people in the store took it upon themselves to come up with a no bike policy I'm sure.
I watched a guy in KMart, completely ignore the staff trying to stop him from bringing his bike in. He walked to the aisle picked up his merchandise, went to the courtesy desk to pay and the only response anyone got from him was, "sorry". He was in and out in less than three minutes.
That was almost a year ago and we still haven't been attacked by terrorists.
