LMAO at motherfuckers thinking GAS IS FREE!!!!!!!!!!!! And that people really want to risk their car and safety so your fat ass can get a pizza. Lol.
Tip up or be known as a cheap ass prick. Bottom line. And is $2-$5 really that much? So what if the place has delivery charge. Do you really think you are gonna get free service this day and age? With the way gas prices are?
And also remeber the pizza guy know's where you live, your phone number, and maybe your credit card number. So watch yourself.
