"Excuse me" is the word.

I walked into Walmart on University, the worst Walmart in the city, trying to use the restroom once again. I walked right in, looked to my right (where the restrooms are typically located near the front and center of the store) and saw nothing helpful. There were two employees standing near the entrance talking.

"Hey," I said loud enough that they could hear me, "where's the restroom?"

One of them pointed dispassionately toward the left corner, past customer service. I could tell she was upset that I'd interrupted the conversation. But there's time to be polite after I know where to take a piss.

"Excuse me is the word," she said with a tone of indignation.

"Actually, it's two words, and you're on the clock so shut the fuck up."
