Today at the local grocery store I place my folder into the cart as usual and pull the cart around the store as I shop.
I have some friendly conversation with the checkout guy- He's apparently a bike guy and commented that
mine was the second folder in the past hour that had come in to the store.
Anyway the store clerk comes over and says (I'm paraphrasing) "I'm kind of embarrassed to say this, but another customer has complained about your bike"
Clerk: The customer has said that the carts are for food and putting a bike in it would make it unsanitary. Next time, we'd be happy to keep your bike in the manager's room while you shop.
Seeing as I couldn't confront the complainant and really the manager was just stuck in the middle, I just said "ok" incredulously and left. Not sure that arguing would have done anything so I figured leaving was the best option. My bike with internal hub is very clean other than some dry road dust on the tires- no more dust than would be tracked in by, say, someone's shoes.
Hopefully I'll be getting some ikea bags soon for situations like this but what chutzpah of someone to complain!
