Thank you for all the replies and I completely understand those who are saying, essentially, "Maybe it's you." It's a valid observation.
First, the "No picnics!" issue has come up in multiple places while in Switzerland (I've photographed the signs because it's amusing at this point) where, essentially, if you're not buying something from the immediate location you're standing where there's a sign like that, you should not plop down and take a load off. No relaxing or getting your bearings or using those seats or benches to have yourself a snack. The first time was in the train station in Luzern. It was in the middle of the open thoroughfare where there were tables and chars set up underneath an escalator. My family had no idea it belonged to the cafe some distance away. The person was very nice when they asked us to either buy something or leave after we were sitting there a while. So, after that, we were very keen on seeing whether there was any signage asking for there to be "No picnics" (there are a lot of those signs here in Murren). Still, as I've said, I get it, I understand, and am trying to roll with everything that pops up.
As well, and I should probably have mentioned this as well, I'm incredibly introverted. I don't get out much, I'm a people-pleaser (that whole American as a Labrador coming through), and I genuinely don't want to upset anyone. Also, I haven't left the country since 2002. Since then, I've had a family, and bringing four other people who get to enjoy everything without ever having to plan anything maybe is a little stressful.
However, being someone who just enjoys to observe people and can pick up on subtle emotional cues fairly quick (if I had only one super power that would be it) I've had the pleasure to meet lots of wonderful people. Our guide in Auschwitz who does tours and was with us for six hours was a delight. Same thing for our guide in Oskar Schindler's factory in Poland. Here in Switzerland we've had great experiences with people as well but after a couple of incidents (one involved something our daughters were looking forward to, eating fondue in a gondola in Grindlewald, and that I paid for months beforehand only to have them tell us after they got dressed up that they gave away our reservation to someone else) I'm sure it's perhaps just me not being able to cope that there are going to be speedbumps.
And, no, I wouldn't want anyone to roll out any emotional red carpet for an American. If anything, I'm just trying to blend in with the local culture and to not bring any attention to myself. I've already seen behavior from other tourists from other countries that I absolutely abhor (i.e. rushing to get into a train before everyone has a chance to exit) and, like someone else said, maybe I've watched too much of Rick's videos (haha) and I've subconsciously think that should be the way it is.
So, apologies for the length of the post. I just don't travel like many of you do. It's taken me over a decade to afford this trip and I know the intended purpose, to show my girls a world and culture outside of their own and that the world can be a wonderful place and to get a little bit of that wanderlust that I've always had but never could afford to satisfy. Who knows, maybe it's because no matter how hard I try I look and sound like a tourist in a tourist town with dozens of other tourists taking over these people's village that there may be some natural friction.
Thank you, once more, for everyone who responded. I didn't think my post would get any reaction other than "Get over it, chump" but I appreciate all of your perspectives. :)
