Queenie53 - I was recently in the gift shop of a London gallery waiting to pay. There were three tills and two young women assistants, one serving the customer in front of me. As the sale was completed the second assistant, who was standing close to the other assistant, rather than near the other tills, excitedly launched straight into continuing a chat with her colleague. It included the words 'So he said "Is anyone serving here?"'
I was unable to resist interrupting (cheerfully) 'Is anyone serving HERE?!'
The chatting young women leapt to her till and, head down, fiddled with it. The other one, who had been looking slightly uncomfortable while her colleague chatted to her, served me. I thanked her and left. I hope a lesson was learnt!
In the 1950s and 60s I came to hate the formulaic 'Can I help you?' and grudging, condescending use of 'Madam' which some department stores and ladies' wear emporiums (emporia?) insisted their staff must use. I also have responded to 'dear' by calling them dear right back.
Like several other posters, I now don't really mind anything I'm called. I'll even accept 'Mom', and love being called 'Bab' (local term for small child!) both by market traders. I don't particularly like being referred to as 'the lady' by one assistant to another and sometimes bother to say (cheerfully) 'Yes, the lady would really like one of those.'
I do compliment assistants on nails and once commented positively on the unusual pattern of the very visible underwear worn by the young man serving me in a sports shop...
