Funin, I hate to say it.... but.... I reckon you had them wrong in that pub. They were actually thinking "well there goes the winner of the nekkid wheelchair race"
Seriously as someone else said, it can be a bit daunting at first (the whole do you kneel.. etc), but one of my mates who is wheelchair bound has an evil SOH and seems to gather a crowd every time. AND, he gets to ogle breasts without being criticised.... every cloud... ;)
