I love Jersey Mike's. The food is consistently good and they have a quality product. I just don't get WHY a fast food restaurant is asking your customers if they want to TIP? Cooks don't get tipped but servers do. This is a Fast Food restaurant not Casual Dining where tipping is expected because the server makes less than minimum-wage. A server depends on the tips to make up the difference in their hourly wage.
If you feel your Staff needs to be tipped, my recommendation is, pay them appropriately. Jersey Mike's is a Fast Food restaurant and asking your customers to tip the staff in not appropriate in this situation.
In closing, I would also suggest you re-
visit your customer demographics. The stores music selection is incredibly inappropriate for your customer base.
