Thanks jon. Of the two handhelds, the touchscreen that looks like an iPad vs the one that uses a stylus, which one is your preference? The portable printer on the waist doesn't seem robust or fast enough to do the job. so is the workflow for a full serve customer: go to the customer, go to printer, than go back to the car. I'm not sure I would want to eliminate our cashier -- our gift shop brings in $300-$600 a day and keeps our customers occupied while their car is getting completed. Our cashier isn't really a cashier; she's the barista, gives away water and asks people to follow us on instagram etc. looks cute and acts friendly, answers the phone --- it's really a command and control center position for both the car wash and lube express
