I have a part-time job where I work in a retail store, serving a mix of customers, from homeowners, to small business-people, maintenance personnel, and a large percentage of people in the construction industry. Our stores are well-lit; attractively decorated; and spotlessly maintained. Over the six months or so that I've worked there; I've gotten very high reviews for my customer-service skills, salesmanship, work-ethic etc. (Not to toot my own horn but merely to put the following story in context.) A couple of days ago, me and a colleague were working with a customer on a somewhat technical question, when I noticed two young guys walk into the store. One of them, in particular, stuck out for a couple of reasons: One, he loudly commented that the prices on some of our products were higher than they were at a competing firm. And two; he was loudly chomping on a sandwich, which he proceeded to wave around (dropping crumbs on the floor) and chewing with his mouth open. After a couple of minutes, the two guys walked up to the counter, and the sandwich-chewer loudly asked if someone could wait on them. To which I replied: "I'll be happy to help you when you are done eating." This obviously surprised the guy. He sighed loudly and put the half-eaten sandwich behind his back. I don't mind working hard to help customers - they are the reason we are in business, and the reason I have a job there. But, IMHO, this crossed a line of acceptable behavior. We don't have a sign on the door prohibiting food or drink in the store (and to be honest, I' have no problem whatsoever with someone drinking coffee or soda while I work with them) - but standing there watching this guy masticate was more than I felt like dealing with. I have no idea whether his behavior was deliberately designed to be offensive and disrespectful, or he was merely one of those people who never learned the value of good manners. To give further context, I've helped literally thousands of people, dressed in everything to grime-spattered rags to business suits. And I'd never encountered someone actually eating and expecting to be waited upon. Did I do the right thing? Have other people encountered similar atrocious behavior in a retail setting? Does anyone have suggestions on how I might otherwise have handled the situation? Or this merely further evidence that the Apocalypse is at hand?
