Someone tweeted that a Facebook page has been created (hit the "like" button) that Krstic leaves bigger tips than Perk, but that Perk would always flush the toilet immediately after using the restroom. There is a running debate on which of these socially polite deeds is better.
On one hand, I can appreciate those who flush the toilet...but then again, I can also understand how the big tips could be worthy of higher praise...
