President Obama's personal credit rating seems to be doing just fine -- because the Commander-In-Chief slapped down some plastic to cover the bill at a burger lunch yesterday ... and tipped more than 35%.

Obama hit up Ted's Bulletin restaurant in D.C. yesterday where he surprised a group of campaign volunteers who had won an essay contest.

Sources connected to the restaurant tell TMZ ... the President ordered a plain cheeseburger, fries, and side salad ... and an ice cold glass of water to wash it down.

We're told Obama asked for the bill personally -- and picked up the tab for the entire group on his credit card. In total, with tip, Obama dropped over $200.

One person who was inside the restaurant tells us, "He couldn't have been nicer."

The "surprise" wasn't as impromptu as it seemed ... we're told secret service swept through the restaurant with a K9 unit earlier that day -- and the restaurant was closed to the public.

"Pawn Stars" badass Chumlee tells TMZ, he has ALWAYS wanted to see a samurai versus a tiger in a fight to the death -- so he did what any person would do in that situation ... he paid a tattoo artist to ink the violent scene on his leg.

According to Chum, he's already sat through three lengthy sessions at Show Room Tattoo in Vegas -- and he's still got about ten more hours of inkwork to go.

It should be completed soon -- but Chum's not looking forward to more needle-to-skin contact ... telling us, "To those who say it doesn't hurt to get tattoos, stop lying! Every time I go it hurts worse!!"
