I don't hobby a lot. When I do, I like to see new people typically, as that is part of the thrill of it for me. So when I am looking to hobby, it is usually on weekends, so I will go through the weekend lineup and provider ads and find a handful of providers that look interesting and PM/text all of them finding out about availability, maybe asking about rates, menu, etc. Based on who gets back and what I find out, basically the first one that I down to details with, I make an appointment with them.
At this point, I might have another provider or two that I have been texting or PMing. We hadn't gotten to the brass tacks of setting a time or agreeing to meet. So at that point, does etiquette say that I should tell them (as well as the 2 or 3 providers that always seem to respond to me the next day) that I found something else, or is it ok to just stop planning then assuming they'll figure it out? I admit that I have mostly done the latter, but once or twice, I got a harsh response from a provider for that.
I can blow off those harsh responses pretty easily if I am in the right, but if I am in the wrong, I would like to know so I am not an asshole in the future.
