If there were over 13,000 rat tails found in the hamburgers of a San Diego McDonald's franchise, then yes, the public will think twice before attending a McDonald's in Maine.
There's a negative public perception about what's going on at Comic-con and women who normally attend these things in skimpy clothing will not be.
Especially not young women whose parents won't let them. It's laughable to compare a one-time single incident at Burger King to WIDESPREAD vast groping across the entire spectrum of the female population at a comic-con.
