I would have to say that at a minimun the guy shows very poor judgement. He has all year to wear that tie, but to wear it the day after the Bears get beat...I simple do not understand why someone would do that.
Can he do it, YES...Does he have right to do it..YES, but just becasue you can do a thing does not make it a good idea to do it. If sued his boss will say that he was concern about he potenial impact the tie might have on would-be customers. THe boss would say...it does not mean he could never wear the tie, just not so soon after a hard lost. And altough we know that people should not take sports so seriously, some do and we have to respect that, after all we are in sales"
Should not have worn the tie
