how is any of that the customers problem… thats the shops issue, not the customer. the customer is paying for a pizza to get there, all those other issues are none of my concern. If the weather is cold and/or its raining i will tip better but its still doesnt change the fact that delivering pizza is the pizza guys job…why should he get an extra pat on the back for doing what someone is paying him to do? how does ordering a pizza make you a lazy ass? do you pay someone to fix your car? do you pay someone to cut ur hair? its a service just like any other.
