normally I do, but have only ever had fairly minor work, involving one or two people for 6 weeks or so. Now we're having major work done - will take at least 20 weeks and involve loads of people coming and going etc. So - being purely self-interested here - does making tea mark you out as a nice person who's worth doing a good job for or as a mug? And on a less self-interested note - is it just good manners or really not expected?
