I think us Americans are far too polite at the TSA. We need to start treating the TSA process as something sacred such that if you fuck it up by not taking your fucking jewelry off you get yelled at. Other countries have similar offensive sacred rites. The TSA is ours.
With that in mind: What are some things American tourists do in your country that is so offensive? Then, confess if you’ve held up the TSA line because you forgot to take your shoes or metal off, or forgot to take crap out of your bag. Should the TSA be like your thing?
