Friends survive eating at a dodgy fast food hamburger place known for something else

As part of a gala evening, two friends decide to be adventurous by eating at a dodgy hamburger joint. Next day one friend realizes that the name suggested wasn't just made up on the spot, but actually known as Hooker Harvey's. As there didn't seem to be any hookers there that night, it was more like Hangover Harvey's. Either way, the sandwiches they ate were actually pretty good and they didn't get sick. That might explain the somewhat confused look on the employee's faces when the friends actually ordered food; actual legitimate customers. It would be interesting if that location had shirts that read "We actually ate at Hooker Harvey's ... and didn't get sick".
