I was speaking with a friend who mentioned that she gave a moderately expensive box of chocolates to her plumber after he did a small job for her. This got us talking, as I was surprised....I guess if you have had a big project like a whole bathroom done, maybe, although I have genuinely never thought to gift anything to the tradesmen who have worked in my house, and I've had lots over the years. Now I feel bad...is this a thing? Do you regularly give plumbers, builders, carpenters and similar gifts of wine or chocolates etc?
