Here are a few:

Construction sites (my favorite)

These are usually free and you can make your entire days profits in just 2 hours a day or so.

Warehouse and factory parking lots.

Most factory bosses and warehouse owners will let you set up on their property once you explain the benefit that their employees who eat with you stay at work and have no excuse for returning late.

In office delivery.

Don’t have a cart yet? Just make up your dogs, wrap them in foil, place them in a cooler and hit the biggest office building in town.

This is a great way to start even if you’re flat broke.

I hope these few tips help. There are tons of great locations that work that you may never think of.

I’ll try to send you some more later.
