Just because someone is blind doesn't necessarily make them unaware of their surroundings. They can hear a cash register and/or receipts printing, and in the off chance they can't, they'll recognize the entrance of the restaurant probably due to a draft. Since most registers are near the entrance, they'll know they're in the right place when they sense another person. Blind people can get around just like anyone else, they just use their other senses to replace sight.
