WHEN New Yorkers are buying their coffee from Starbucks, it's unlikely they're thinking: Just how erotic are the toilets?

One man is and he has made it his mission to visit, defile and rate every Starbucks bathroom in New York City. That's 298 in total.

The New Yorker, who calls himself Mister PeePee, been tweeting his progress since he started in December last year:

"Today's Starbucks visit is rated as a 4 Boner. Spacious, clean, excellent coffee, strong wifi, no interruptions & 1 hot chick."

In a podcast that's since been removed, he explained that bathrooms lose points if they are unclean or if a person knocks on the door and interrupts him.

His mission isn't endearing him to Starbucks employees, especially those who have to clean the toilets.

One wrote on Starbucks Gossip: "Glorious. For everyone 1 of him who decides to mention it, think of how many don't.

"We have one regular who comes in for about an hour a day and stares, yes, stares, and studies, the baristas working."
