The following scenarios are actual experiences that have happened to me recently.

Scenario #1.

You unwrap your soft taco (from Taco Bell in my case) to add some sauce to it and notice, what appears to be a fingernail mingled in with the lettuce. You analyze the mysterious debris, yet you can't fully determine whether or not its a fingernail or perhaps just a mishappen piece of lettuce.

You toss the suspicious element in the garbage and now the question comes...Do you eat the rest of taco or no?



Scenario #2.
A wasp lands in your uncovered Frosty (chocolate milkshake treat) and scampers around the frozen surface. Apparently, he's been frolicking about the surface for quite some time, cuz he has left a number of tracks.

After shooing it away do you continue to finish your Frosty or do you toss it?



Scenario #3.
Your at a deli and the guy making your sandwich coughs and covers his mouth with the back of his hand. He goes on to finish preparing your sandwich.

Even though he coughed on the back of his hand, do you feel that his germs may have still found their way onto your sandwich or do you say "screw it...I'm sure the rest of his hands are still clean"?
