I'm sure they have to draw the line somewhere but it's unclear what that line is. I also think it really has to do with people bringing in coolers to have lunch on a bench or something.Wonder also about whether that means ALL food, or just people bringing in coolers and such.
We tend to bring in snacks like pretzels and Pistachios. I would probably continue to bring these in. More upsetting would be if they stopped us from bringing in our bottles of water. I know they give out ice water at the counter service, but I'd much rather be able to re-hydrate whenever I want without having to push through a counter service line-up to get it.
