I do pay this sign waver actual wages. Hes my employee in the shop too. When sales are slow, out to work the corner you go! Before they ban sign waving, they'll have to ban the people pan handling on the same corners.. I shit you not I see this sign the last 3 weeks. Going back to college this fall. Need money for school clothes.
I do see where the sign waver could be too distracting. However if it gets banned, it'll serve as a second sign.
Right now I typically have the sign waver out there during lunch hours and rush hour traffic home. What's different about my business is on Sunday a customer came in because of the sign waver. Spent $300. Then they came back in yesterday and spent $17, to start setting up their daughters tank. So I profited roughly $160 on those sales, paying for roughly 16 hours of sign waving. The thing is, these customers will continue to buy on at least a monthly basis. In the food industry, you might only make $3 on a plate of food/pizza etc... At that rate it's not worth it.
Another great thing is, if the sign brings in customers right away, I just text him and tell him to head back and help get the customers in and out. I plan to just make this a requirement for my employees. When business is slow, you can either go home, or wave a sign. But we can't just have 2 people doing busy work waiting for people.
