Tourists ask a lot of questions and a guide should be friend, helpful, and approachable. Guides shouldn’t claim to know everything - we’re not superhuman! If you don’t konw the answer, say so , but add’ I’ll find out for you. Questions can vary. They can be practical ones; it’s important to know where the toilets are situated as well as the date of a monument! When things go worng - as they occasionally do - a guide should pause and calmly sort out the problem, and try to make sure that the original itinerary is kept to.
