Ok, so the crockpot idea has given me pause.
How often have you done this? Do you have an "old crockpot" shelf? Do you buy old crockpots all the time? Why is buying old crockpots and leaving them around airports better than bringing, say, a sandwich?
What do you cook in it? Do you transport warm/hot food in it? How do you get the food through security? You can't bring liquids through, so are you buying "cream of___" soups after the security checkpoint? Where do you buy cans of condensed soup at the airport? What airport allows this?
Do you wash up after? No leftovers? Or do you take your barbecue shredded pork on the plane? Do you leave a note, saying, "free crockpot!"?
Do you know if security has ever had to explode one because a crockpot could be considered suspicious, sitting unattended? Do you worry about security finding an unattended crockpot and tracing it to you and getting in trouble?
Thank you. Please answer, so I can sleep tonight.
