Guests in Lines

This is somewhat of an odd question. But I'm curious. I'm sure I'm not the only person to ponder such a thing.

I'm sure we've all seen that couple in line that WON'T keep their hands off each other. I'm not talking about a back rub or a small kiss. I'm talking about an all out grope-fest. The kind of material parents would certainly not want their kids to be exposed to.

My question is: At what point do employees have to step in to tell the frisky couple to hold back a little bit? Have any of ya'll had an experience with people like this? If so, how did you handle it and how did the couple respond?

Weird question, I know, but I've seen some stuff I wish I would not have in some longer lines.

"We would like to remind guests in line this is the Top Thrill Dragster queue, and not the Love Shack, and that smoking is only allowed in designated areas of the park, thank you for being mindful of other guests, and enjoy your day at Cedar Point Americas Rocking Roller Coast"

Let's see...Silver handrails, smoking, lovemaking...nah. Nothing out of the ordinary. What really is bad is those who don't wear a shirt, ha.

"Excuse me, Cedar Point is a family park, not a park for making families."
