I have no idea of your expectation of every tour guide you will experience but if this is a "group" tour, the tour
guide has to accomodate the "masses". Sounds very reasonable for a "group" tour guide to ask that you hold your questions and he or she will probably address it in their regular presentations. The guides are usually also responsible to keep the "train" running on time. They have to meet time deadlines and get the most information to you in the time they have allotted. If they open up the floodgates of individual questions during their talks at each site, there are distractions, delays and everyone suffers.
Judging from your dismissive "whatever", sounds like you might be an immature kid in an adult's body. Only junior high kids on groups tours get upset because they can't interrupt the tour guide when they are speaking inorder to get your personal spur of the moment thought addressed. (whatever dude)
If this is REALLY your complaint, hire a private one on one tour guide at a higher price and they can be your on the spot
expert at your command.
