I have simple request...no tomatos.  Not because I don't like them, but because they can KILL ME!!\n\nThat means clean gloves, clean knife, cut the bread on a clean cutting board or as a minimum a clean piece of paper under the bread.  I only want onions on my sandwich...can you please get them from the back...not from the tray where you've previously dipped you tomato contaminated finger into every vegetable on the line.  To include the onions I want.\n\nI know you have a system where you make sandwiches quickly.  But for gods sakes, slow down, listen to my instructions and do it the way I ask you.  You screw this up I end up in the hospital because my breathing has stopped (BTDT...no fun).  On the other hand you slow down for 1 minute, you save a life and make a customer happy.\n\nIt only took you 3 tries to get this right.  First try I just walked away because you clearly weren't listening to my needs.  Second try you delivered a sandwich, when unwrapped, had several tomato seeds (enough to KILL ME) between the paper and the bread.  Last try...success.\n\nWouldn't it have been better for you to listen to what I had to say and slow you crew down so they understood exactly what they were dealing with?\n\nIf someone tells you they have a food allergy, especially one that is easily accommodated, pay attention, do what they ask...you just might save a life.
