OP here, I love all of the comments you have written :D I didn't think this would get published. But to answer some questions the puke did get all over my shirt, the man apologized to me before stumbling out of the store, and my boss let me leave early. I did not have to clean anything but myself. Maintenance took care of it and they shut down the register for a while to take of it. Thanks for the comments guys :D any questions feel free to message me.
