Romola
Sorry, but I'm going to have a tiny rant about the users of motorised wheelchairs in shops and supermarkets.
Please don't propel yourselves at wheelchair top speed up and dow the aisles. You really could hurt someone who isn't as nimble as they were. Actually the main offenders are men.
4 miles per hour is the speed limit of these machines on the flat, which is a brisk walking pace not top speed, but I agree this is too fast for many dawdling and wandering around the aisles.
Since COVID , people seem far less aware of those around them, and also less inclined to watch where they are walking and move out of the way of others. I am able to walk, but find it frustrating when I want to shop at a reasonable pace.
