Sports Direct Outlet Store.
Went in on my lunch to get some new trainers, picked some that were already out to save having to wait for an assistant and got in the queue. There was one guy already at the counter and an older gentleman in front of me, one guy serving.
The person at the counter was disputing the price of one of his items so the checkout guy called over someone to help him out. This 'help' took a good few minutes to come during which there was zero activity on the tills carried out and by this point the queue had grown to around 12 people.
Now we have two guys on one till, tapping at it like it's something they've never used before and the dispute doesn't seem to be any further to being resolved, this went on for another 5 minutes. The man in front started grumbling to me and I could hear people complaining between themselves behind me.
Another few minutes pass before the 'help' decides to go off to check the price on the shelves of said disputed item (which of course was right over the other side of the shop) and as he does the checkout guy just stands there looking vacant. The queue is an aisle long now with around 25-30 people in it.
I finally crack and say to the checkout guy "Excuse me, whilst your colleague is resolving this issue could you not jump on to one of the other tills (there were 4 free) and start serving us?" He looks at me blankly then just ignores me.
The customer being served turned and agreed, apologising to me and saying why he can't understand why the checkout guy couldn't serve us now he had someone looking at his issue. The gentleman in front turns and says "well done, you were right to say something" (clearly glad he didn't have to do it).
Another few minutes pass and the 'help' comes back this time with another guy who finally jumps on one of the spare tills and starts serving everyone else. The crowd all cheer in unison.
Should have been a 5-10 minute job, ending up taking about 40 minutes.
