I was browsing for stocking fillers for the DC in Hawkins Bizarre (as I like to think of it) yesterday, and every time I so much as touched a product, one of the staff members came up and told me how much fun it was and how it was their favourite thing in the shop, in an attempt to get me to buy it. In the end, I had to request that they back off, because my peri-menopausal head couldn't cope with all their chatter when I was trying to work out what tat to buy.
The same thing happened in Body Shop last year. I was happily browsing the gift sets and I had 5 or 6 approaches in succession from staff members desperate to help me in my purchasing decision. I just wanted to look, compare and think ffs. I'm afraid I lost it and snapped at them to be left alone in the end.
I know sale staff are under instructions to be chatty and help. But if a customer has been approached once, surely that should be enough.
