if you cant justify it yourself, maybe what they are saying is true. you should be able to come up with a reply on your own. think of the benefits of it and tell her that. for example: "while youre dealing with bitchy customers at work, i get to sit on my ass, have fun, and make money playing poker"
dude i work at Hobby Lobby and that is pretty bad... I usually say at first "you know those guys you see on highway exit ramps begging for money? well, they all work for me" and then when i finally have to tell them where i work, i say something about how the hours are good, i dont have to work sundays, i get to break stuff without punishment, etc. usually after telling a chick i work at hobby lobby, they ask if they can get a discount, i can turn that into a neg real quick
Stack into something and set up another meeting.
