I forego a greeting most of the time in that situation at home improvement stores, but I'm not great with people. My thing is I just am walking and I see an employee and I'll barely pause in walking or speak before I get there and not stop walking at all and I'll go "I'm looking for (whatever)?" or "where could I find (whatever)?", that kind of thing. They tell me where to go, I give a thumbs up, say thanks and keep walking. I want shit to be as easy as possible for everyone. I would never go up and bother an employee while they had their hands full or were already helping customers, because I have a basic level of consideration for other human beings.
Since I read this I've made an effort to be even more polite than usual. Mission accomplished Mr. G.
(theoretical customer) --- hey asshole, give me paint supply. unga bunga.
your problem is that you're dealing with people who are spending more than they are comfortable with to make a bedroom medium fuchsia. personally, i'd pay good money to not have a bedroom painted medium fuchsia. i might even be rude to an associate of a hardware store, and, were they not helpful ... i'd tell my spouse we can't paint the bedroom medium fuchsia because of that guy at the store.
you're really letting us all down by helping us paint that bedroom medium fuchsia.
here's a tip, next time ask people: would it be worth your while for me not to help you?
it's like a reverse protection racket: a deflection racket.
(also, paragraphs and commas help break up a long thought into parts, which can be read without exceptional effort. try saying out loud what you type, and listen to how it sounds. run on sentence extravaganza here, but i feel you mang.)
