don't ever make them feel stupid.
Back story: I took my boat and motor to a marine shop to have it (the latter) looked at. The place is right off a major street in town and the parking lot (where my boat would sit) is only a few feet from the sidewalk. There is no fence around the establishment and the town itself is not exactly a crime free community. Prior to bringing it in, I had asked about this (security) and the owner said to take off anything that I didn't want stolen. As my boat is an "open air" design, the portable gas tank, fuel line, and the cranking battery are readily accessible and can be absconded in under 30 seconds and, having never brought a boat in for servicing before, I took the shop owner at his word and, stupidly, left the battery and fuel tank home-figuring since these items are interchangeable (after all, it IS a marine repair shop), he could easily hook said items up. Today he calls me and asks where these items are. Innocently (naively) enough, I said that I did not want it to be stolen so I had left them home). And, again, I said that I figured he could easily connect these things. He said, "how can I work on your boat without gas or a battery" and "you wouldn't take your car to the shop without them, would you." (Truthfully, no but a car is considerably more secure than my boat is). also- "...I am to bring said items to him if I want him to work on it." Prior to this phone conversation, I had been nothing but very polite to him but afterwards, I thought, "You know, this guy sure has a knack for making me feel stupid. (And a couple of other things I wil censor out). I am not the thickest skinned person in the world but to borrow a quote from Maya Angelou, it isn't what people say or even what they do that you will remember. It is how they make you feel.
For those of you who feel the compulsion to say I should have known better", perhaps you are right but this is not the point of this thread.
