What are some creative ways of dealing with a queue jumper?

This on the road, or in the supermarket?
I’m new to this word.

Either/or mate, anywhere where there’s a line of people/traffic.

In that case: kill ‘em!

Summary execution

Pick up a tube of rash cream and then sneeze on them.

Help @rebbel kill them.

If driving I will not budge for lane jumpers. They get so mad. Happens almost daily commuting. I get flipped off a lot lol.

Social outings, I dont care unless its a premiere, then the others in line rally to shame them out of line. A recent movie was sold out, a couple tried and tried and we all shut them out since they came very late, and we’d all waited over an hour.
