You can’t work past 11pm, well at least according to this article.

Edwin Hardee, who operates a hot dog stand on Saturday nights outside a
popular Thomasville pub, said he would have to give his permit back to
the council and move his business to another town if the time
restraints were approved.

?I?m one man,? Hardee said. ?I?ve done
everything required of me to get this permit. I jumped through all the
hoops and I was happy to do so. But if I can?t stay open past 11 p.m.,
I?ll have to pack up and go somewhere else.?

Councilman Scott Styers argued in favor of the time constraints, citing pubic safety issues for the vendors.

?I
worry that because these merchants deal primarily in cash, having them
on the street late at night could provoke higher risk for possible
violence,? Styers said. ?We just want to keep everybody safe.?
