I have more patience for traffic lights than lines. Any time I see people lined up outside some restaurant for brunch on a Sunday morning, I think "The food can't be that good! It ain't worth the wait! Here, folks, follow me to this place called 'McDonald's' where they'll cook you up a breakfast just as good for a fraction of the cost, and there's no waiting!"
Amusement park ride lines where they either have monitors to amuse the hoi polloi or signs indicating wait times "from this point" means it's too long of a wait for me. No thank you. Unless it's "Pirates of the Carribbean" at Disneyland, in which case, there is never too long a wait.
Grocery store lines drive me crazy, and social distancing protocols over the past 15 months haven't helped. What I don't get is how difficult it is to form a straight line. I mastered this in kindergarten. But I can't tell you how many times the person who walks up after me decides to join the line at a 90º angle to me rather than get behind me. Then before long I've got one or more person or persons behind me and one or more to my right or left. And almost invariably, the one who joins the line at a right angle s-l-o-w-l-y tries to creep in front of me. Not on my watch, pal! I'll creep ahead of you just a little bit quicker. I can be very passive-aggressive when I need to be! It's one of my most endearing qualities.
