It's at times like these that I miss the U.K. culture when it comes to how customers react to tradesmen in their house. Here the day is always the same, irrespective of customer.
Start 7 a.m.
Breakfast 9 a.m. for 30 minutes, customer doesn't offer you anything.
11 a.m. coffee break for 30 minutes, good customer offers you coffee and a cake. else just drink your own coffee.
1 p.m. lunch break for 30 minutes, customer may invite you to sit at the kitchen table to eat your sandwiches, but you drink your own coffee! Oh no, you don't get TWO cups of coffee, not out of a Swedish customer!
4 p.m. finish work. (Optional to stay and work overtime).
Betweem those breaks the customer will never come and offer you a drink, or food, nor are you allowed to stop work to have a cup of coffee or anything. A gulp of water here and there does not result in the Polis being called, but if there is even a hint of thinking about grabbing a sandwich then they'll be dialling 112 before you know what's happened.
