I get that sometimes it is an accident that you hit the change button. You know.. If you hit it again.. It will turn off! Interesting idea. I hate when I come up to a change light and there is a stupid looking person with their arm sprawled out on the machine. I ask “would you like change?” they look at me as if I just spoke pig latin and I repeat myself. Then I hit the button, and let them know that anytime they hit that button… I need to come down here and make sure it wasn’t an accident. Some people get it, some people think its funny to run my ass around, and some people didn’t hear my speech and continue to keep accidentally hitting the change button. Then, I will stand behind them like an angry mom with my arms crossed waiting for them to dare touch the button again…. I will break fingers…
