My local Home Bargains always have around 2 out of 6 tills open. They, for sone reason, wait until there is a que all the way down both aisles until they open another till.
Also covid wise: it's hard to socially distance as they have long ques going down the aisle so you're more than likely going to be in someone's way of reaching for an item they want and if you try to step out of the way, you're close to someone else.
Are all Home Bargains like this?
