FRC rules around seating need to change.

[Chris is me]

... If you need your six scouts to have six seats, why don't they just sit together at the beginning of the day? Where do they have to be other than in the stands scouting? Hold your seats like everyone else who follows the rules does.

If one or two of them has to get up and go to the bathroom, other teams aren't vultures who are going to come down and take those two seats, particularly if they are scattered amongst your team already. Most people are gracious enough that if you politely say that the one seat they are sitting in was occupied by some dude who will actually be right back from the bathroom, they'll move out of courtesy and not because you made them.

You do not have to break FIRST rules to scout, and it's honestly appalling to see veteran, well respected teams encouraging the practice in this thread. It's first come first served, even if your region of the country ignores this rule...
