I hear some companies would introduce veils for everybody, but then some will still have ugly voices to alienate customers. And then some people have more metal in their faces than my car has. And blonde service girls have an undue advantage. And fat service people are... better for fat customers to deal with? I do not quite get the rationale here. When people in a company have to deal with clients you should probably not offend them by having a tattoo in their face that reads: Customers Suck! .
A former boss of me once said: And when we see the client you should wear reasonable trousers. I still until today do not know what he expected, since I did wear a suit and I did wear it when the client was seeing us. So yeah, we must accept clients the way they are, and vice versa, plus we all do behave better than an average customer. I think to be friendly, civil and reasonable and washed and wearing clean clothes and not looking like a zombie is something I expect from everybody outside of a slum or catastrophic event. When staff has tattoos, so what? OK, you should not have ink on your forehead with offensive messages, but well, a bit more relaxed civilised tolerance might be better than a no tolerance policy aimed at tattoos or anything else.
