This happened a while ago, but I still wanted to say this arena did nothing wrong. Most of society thinks taller always equals bigger, so what was the problem?
Show people a tall lean guy, then a short stocky man who weighs the same or more. Most will say the taller guy is "bigger." People wanted a larger beer, they got a taller cup.
You reap what you sow, or does this not apply to drinks? Just saying, you played yourself.
