Am I a grumpy old man and a problem customer ?

One of my local supermarkets has adopted a stupid (in my opinion) method of counting how many people enter the shop during this whole pandemic. They are demanding that every customer who enters must take a clothing peg which is drenched in disinfectant from a bucket at the entrance, carry it around the shop and hand it in at the exit again.
This is a modern supermarket with all the electronic bells, whistles and surveilance cameras etc. but their high tech method of counting customers is clothing pegs drenched in slicky liquid...:-)
