Temporary Airbrush Tattoos

Has anyone got any bright ideas on how to end your queue. I have tried everything from given out tokens, fluorescent jackets saying end of line, verbally telling people. I already hike enough kit around so don't want to add to it if I can help it.

What do you guys do?

My daughter is normally on crowd control, she takes the cash(makes them wait then) hands them a "how to look after your tatt" flyer and writes the design number on it so I know what they want.

That's a good idea. My daughter is only 6 though so not quite old enough. My 19 year old is not interested to get involved so down to just me and Gaz to organise.

I like that idea though so will maybe enlist dear daughters help when older. Will keep her occupied.

I just tell my customers where to wait because I work by myself as well.
