Use the Powder!

You grumble and grab the powder again, tossing some into a bottle of water you steal off of a guy walking by carrying a case of them. You gulp it back and belch as you concentrate on your wish. This stupid door wasn't going to be holding you back!

"I wish this stadium was big enough for me!" you yell out, not caring that anyone was listening.

The door in front of you starts to swell before your eyes and the whole building rumbles as it gets bigger and bigger. The place is starting to take up so much more space that the other buildings around it start to disappear to make room for the stadium itself. Though you just smile as the whole street is now dominated by the huge space and everyone around you acts like it was perfectly normal. Seems like your wish was so big that it had to affect the world around you in order for it to actually work.

"Much better," you say as you much more easily step through the doors and go thudding down a now even wider hallway full of people.

The food stand were bigger inside the place now, too, serving several people at once as you waddle by. You smile as you can smell all the delicious, greasy stadium food cooking and going by you as attendees hurry back and forth to their seats with it all. Of course, you also notice the sign that points in the direction of the locker rooms so you know you need to go get ready. But you were hungry...
