I wouldn't make a habit of it, but if it was a choice between eating there or being miserably hungry when I'm supposed to be relaxing, I'd just grab something to eat really quick during the pedicure. But then I'm not someone who can skip meals easily.
I agree. I, personally, wouldn't eat while getting a pedicure but that's not to say that she was rude, esp if the salon didn't correct her behavior. If it was against policy, then I'm sure they would've asked her to put it away. If they didn't, then that is on them and they would be the rude ones.
As for the smell, one meal usually doesn't stink up an entire room unless it's seafood or something similar. One Big Mac meal wouldn't necessarily overpower an entire salon. It smells like greasy food when one walks into McD's because there are large quantities of it but one meal, I've never experienced that overpowering "oh my gosh, I'm about to throw up" smell that some are describing. Maybe some of you are more sensitive but even then, it's one meal in a salon. The other salon smells are more dangerous/nauseating to most than a burger. (most salons)
