I would write a note to the owners of both establishments deatiling the event and the reactions while mentioning the number of bikes (potential customers or current customers) involved and inform both buisnesses that they had just lost that many current and potential customers and that you will not be mentioning either business in a postive note in the future.

Good manners and tolerance are endangered creatures and should be protected along with good buisiness practices.

I am old and crotchety and don't have time or patience for smart alec or I am doing you a service to be in servic groups. I can easily take my money ad walk.

just sayin.
