So many folks live a daily life of scratch and bite that when they go on vacation, they are so ingrained, they can't help it!
We have probably all met the guy at dinner on a ship that no matter what anyone says, he has done it bigger or getter, no matter what the food offerings, they are inferior, etc.etc.etc.
My personal favorite is the guy shopping to see how good a "deal" you got for your cabin. When you run into him, find out where he is , always tell him you are one deck higher and paid $299.00 per person for the ten day cruise.
Makes them nuts!!!
