Worst case I can recall is when we met a couple on holiday. Got on really well, he owned his own pharmaceutical company, a fact his wife crowbarred into the conversation within the 1st 2 mins of meeting them. After a couple of days she found out what I did for a living and basically never spoke to me again. He was great, no airs and graces, just a down to earth bloke who'd done very well for himself. She didn't work, a true parasite who lived off her partner and dined out on his status, yet looked down on me. I tell people what I do fairly quickly these days so as I don't have to waste precious time on total dick heads, life's too short.
