How to Eat a Sandwich

Ok so I am distraction central lately, not sure why, but I am-so when eating lunch today I became very observant of how I was eating my sandwich. And then I thought...is there a proper way to eat a sandwich? For example, when eating a PB&J, should you eat it with the jelly on top because if you had the PB on top, would it stick to your mouth? Today I had a crazy good sandwich from Rosati's that had, Turkey, Cucumbers, Avocado, Cream Cheese and Cucumber Dill dressing...delicious! Except I was eating it with the cream cheese on the bottom so that is all I tasted, then I flipped it over and it was a little better but then I had cream cheese hindering all the other ingredients. This only left me to think that having cream cheese in a sandwich is only a good idea when it is in the middle of the sandwich. Further more....when deli's and sandwich shops create sandwiches...do they think of how they layer the sandwich and which items the person will taste first? Do they think about how a person holds the sandwich? Top or Bottom? Next time I see a sandwich chef I will ask. I feel very Joey from Friends right now by the way...
