Subway, Springville

My wife and I visited the Subway inside Walmart in Springville, Ut. The employee put way too much mustard on the sub and I asked her to remove about half. She took a knife, using it to wipe away the mustard. So far so good. However, it all went downhill from there. She proceeded to wipe the mustard knife on paper inside her counter's garbage slot! Then she re-wiped the knife on my sub! Holy Germs, Batman! Talk about gross! When I asked her to start an entire new sandwich, the employee acted rude, offended, and as if she had done nothing wrong. She said she hadn't wiped the knife in the garbage, but only on paper. THE PAPER WAS IN THE GARBAGE! This was a major health hazard, and has made me decide to avoid Subway here and elsewhere.
