A binman isnt self employed and noone gets a say they turn up
And empty your bins.
A barbers we go to when we want they have a shop
And we usually tip them anyway (unless your a tight git)
and as for professionalism, i think it looks better showing that you arnt scrimping and are willing to spend a few quid to wish the customers all the best:)
If you haven't done it before then thats fine, i always have and just wondered if i was the only one.
I see your point mate, but I think a custy's first thought when they get a card from their window cleaner would be "eh? what's that all about?" rather than "OH, our windy has sent us a card, that looks professional. He must have cash to spare to show us how much he cares".
If I start getting cards off my bin man or hairdresser, or my windy (If I had one) I'd think he's after a tip, or is lining my missus up
As you say, it's upto us isn't it. So good luck, what about a card for me then?
