Before I post, please note this is a PERSONAL feeling and I dont have anything against an adult politely asking for another persons autograph, or paying for it if they wish, its their money and rich guys spend $1000+ on a bottle of wine sometimes so its no big deal to me, but still weird.
As a grown man (who actively collects vintage autographs), I would never ask another man for his signature. I will take my kids to a game and help them try and get autographs of Mariners players, but thats it. Maybe its arrogant and prideful, but I feel its demeaning to me as a man to put myself at the mercy of another man and ask him for a signature. I would just feel like Oliver Twist with his bowl asking for "more". I cant tell you how annoying it is to go to ball gme with my 8 and 10 year old sons trying to get ONE autograph of a mediocre player like Dustin Ackley and the second he appears from the dugout all these grown a** men start pushing and shoving little kids to get a 23 year old young mans scribble, its demeaning and sad. TOTALLY a personal thing so if you disagree please do not take offense. I feel the same way about guys pushing people to catch fly balls at the stadium too, let it go, its a $15 ball!
