Oh well, I never got fired. In retrospect if I ever worked at Target again (which probably won't happen) I wouldn't do stupid shit like that, but what's done is done.
And yeah the whole point of having a hobby is that you take time off being "productive" to do something you like, though plenty of people take "hobbies" and use them as moneymakers - violinists get paid to play at events/record albums, WoW players I'm not sure but there are probably star players like DDR or Guitar Hero players, even shoppers can sometimes land jobs as personal shoppers.
My hobbies are shopping and traveling, possibly two of the most expensive pasttimes on earth, so I'm in no rational position to criticize gamers. It's really only the severe addicts that I feel sorry for/disgusted by, and Our Lord in Heaven knows I'm no stranger to addictions.
That shopping picture speaks the truth, but for going to all the mall stores like that I'd estimate it would take 4-5 hours.
