I often do 5 Guys and do stay the 15 minutes after getting the order but I do not really eat their food. I will look at the burger to be sure it is all there, taste one or 2 fries and get a drink from the machine BUT I do not love their food- my son does so I bring it home for him. I wonder if I really need to sit there 15 minutes- who would know if I did not? and what am I supposed to do for 15 minutes besides look at my phone? I know there is a question about whether there were ever more than 2 people in line but I often sit where I cannot see the register clearly. Does anyone have any idea as to this 15 minute thing and has anyone ever been caught leaving say 10 minutes after getting your food? the shop form says the client watches security cameras- but how do they know it is Me?
