I'm a big fan of word of mouth being the the response to poor service.
Do not patronize the Tea Thyme and Lavender Tea House. The short form: A customer left her car there for less than an hour, after the store was closed, and returned to find she had been towed. Who doesn't do that? The owner was rather rude and claimed once the business closed she was not longer a customer, so it's her own fault. Retriever Towing goes trolling for cars minutes after stores close to rack up charges, and made the same argument. The stores are quite smug in their mutual back scratching, but I'd never go there.
