Not really an AIBU but could do with the traffic! 
I need some suggestions of a thank you gift for let’s say a Plumber (it’s not a plumber but you get the idea) that has gone above and beyond when working on your house.
They will have done nearly two months of work and have done ‘extra’ (done a couple of deals for free extra materials, not charged for certain things to make it cheaper etc etc)
They have worked really hard and done an excellent job.
What type of thing could I get as a thank you? I want something for the boss and a smaller something for his workmate.
I don’t want to spend too much and I don’t want to embarrass them or make them think WTF but I do want to do something.
Please go shopping for me
