DH and I were at a place getting dinner once--we ordered one thing each. We were then given two completely different meals. I alerted the waitress before she had put the second one on the table, "oh, these must be someone else's meals; we ordered <completely different things>." The waitress flat-out said, "no you didn't. You ordered this," and stalked off. We got the manager who also argued that we ordered what we had been given, despite the fact that he didn't even speak with the waitress about it or check anything. He argued immediately from the get-go. Great customer service. We left.
Recently DH bought me some bath soap things (I generally just like nice smelling goop). I used the first one and got a tremendous blotchy rash. My skin then got all scaly and flaked off over the next few days. So, naturally, I returned the unopened and unused soaps, thinking that it would be a waste to discard them, and someone else who doesn't react to them might get some use out of them.
They were very hard to return. "Oh, these are organic, so you can't have a reaction to them. There aren't any chemicals in them, you know." Note that I have a tertiary degree in Biochemistry and don't appreciate being told I cannot return a product because the shop assistant is ignorant of her severe limitations in high-school chemistry. Especially since, according to the receipt, they could be returned within a month without even needing a reason. The manager was just as bad. He got fixated on the apparent impossibility of 'organic' products causing a skin reaction, and became unable to hear my request to please just let me return them anyway regardless of how magical he thinks they are.
Not going there again. No-siree. Both because they use something that gives me weird skin, and because the people working there are idiots who won't listen to facts and somehow won't even follow their own rules as a result.
