I wouldn’t boycott the chain because of the alleged actions of one franchise owner or manager. Let’s see what Subway corporate does.
I have noticed that many of the Subways in my neck of the woods are owned and operated by foreigners. Many of the employees speak English with such heavy accents, I can’t understand them most of the time. Of course, being half deaf doesn’t help either. :)
I do boycott it because it SUCKS!
