In the US tipping is not an option. What is the best way of covering yourself with regards to HMRC and not being out of pocket on a business trip to America? Do you add 10% to your receipts and hope for the best? Or should you allow a per diem and hope that a daily allowance will cover your living expenses?
+1 on this question, we have to travel to the USA for a trade show once a year and this confused me as there didn’t seem to be any kind of official information available!
