RE David Diment’s letter (Viewpoints, September 16) complaining about it being none of the shop assistant’s business to ask if he had a good day.

Mr Diment would feel a lot better if he asked them if they had had a good day and wished them a good day.

If they have to put up with such moaning customers as him, that must be depressing for them.

I like to exchange pleasantries with them and they help a bad day to be brightened.

When I’m wished a good day and see a lovely smile it lifts my spirits.

Mr Diment, a smile or a wave or a ‘have a good day’ greeting costs nothing but makes some lonely people’s day for them.
