(I call BIG FAT LIE on that one, since I know that state (federal?) laws require all places of business to have a restroom on their premises for the employees' use. I know you have a restroom, cute Magic Mouse employee. You could have just said "It's only for the employees," and saved yourself the title of Liar Liar Pants On Fire that you now have.)
Magic Mouse employee will also tell you that the Starbucks across the street has one you can use. So you will leave Magic Mouse toy store, walk across the street, and see that Starbucks has no intention of letting you use their restroom without your becoming a customer, i.e., buying something.
So you'll get in line. Still having to pee. You'll look in the display case and decide to buy a blueberry scone. You'll purchase the scone, ask for the restroom lock door code, and walk back to the restroom door.
While you are waiting at the restroom door, a man will pop out, looking rather alarmed, and inform you that there is no toilet paper in the restroom, and "about four or five paper towels on the back of the toilet." You will find this annoying, still having to pee. After the man informs the baristas behind the counter that the toilet paper situation is dire, you will stand and watch them for a few moments as three of them continue to serve customers and do absolutely nothing about the toilet paper.
You will get back in line, bagged scone still in hand, still having to pee. You will follow the other people in the line as they make their purchases. The employees will continue to do nothing about the toilet paper. You will finally get your chance to speak, and you will politely ask the barista for a roll of toilet paper so that you can go in their restroom and, you know, do your thing.
SHE WILL REFUSE.
She will say, "I'm so sorry, I know we need to fix the toilet paper, and I just can't quite get in there right this minute."
You will be aghast. Still having to pee.
You will ask for a refund on your blueberry scone.
You will get your refund with huffs and rolled eyes (sorry, girls, I'm not the one who can't refill the toilet paper), leave the store, and promise yourself to write a scathing! SCATHING! review of your experience on every online customer review site in the history of Father Al's Internets.
You will meet your family, and then walk five more blocks until you find a wonderful place to have dinner, Italian Family Pizza.
You will be directed to the well-stocked restroom by their very friendly, kindhearted employee.
You will eat monstrous pieces of pizza. (No, seriously, monstrous. We ignorantly ordered two pizzas and were extremely, pleasantly, but overwhelmingly surprised when we saw them...)
You will walk back to the car, very content, no longer having to pee.
