I've been told that I can't bring my bike in at several places, also had folks say the same thing, "I'll watch it for ya." PSSHH As if I'll trust anyone with my bike except a friend. Certainly NOT some random person that I don't know from Adam. Each and every time a place of business has told me that I can't bring my bike in, I simply left and haven't returned since. If they don't want me to bring my bike inside then they don't really want my business. This is of course a non-motorized bike.
When I had a motorized bike a few years ago, I was going through the drive through at McDs late one night. The doors were locked and you could only order at the drive through. When I pulled up to order the lady tells me they do not serve bicycles in the drive through. I rev'd the motor and she says, "Go ahead with your order please." Kinda made me giggle a bit.
