Well, over the course of two and a half hours at a retail park yesterday I, as a middle aged man, experienced the following:
In Smyths, a member of staff was sending a remote controlled car between customers feet at the (packed) customer service desk. When I stepped back to let someone out, I accidentally trod on it and he got arsey with me.
In Asda, no manned check outs were open. At the basket self-serve area the member of staff directed me to a particular till and as I was getting my first item out someone else came up, pushed me aside, and started scanning. When I turned to the member of staff he just shrugged his shoulders and said "he won't be long". This bloke was buying one bottle of whisky and he was drunk, at 11.30am. The staff member still authorised it, all while I'm standing there twiddling my thumbs.
In McDonalds, it was absolutely packed. No manned tills available - screen ordering only. The display screen showing which orders were ready wasn't working, so they were shouting order numbers out instead - the place was utter chaos. It took over ten minutes for my order to be prepared and by the time I made my way to the front, my order had been given to someone else despite the fact I had the numbered receipt for it.
Normally I'm a fairly chilled kind of person but I was ready to explode by this stage. Service staff get treated appallingly because, in my experience, they provide appallingly crap service.
