Checkpoint Stress
Who likes dealing with the TSA? See, nobody raised their hands. Airport security in other countries can be just as bad, and dealing with customs is never an enjoyable experience. However, they’re not there to intimidate you (unless you plan on committing crimes in the country, then yes, you should be very afraid).
In fact, airport security is there to ensure that no bad guys or bad things are smuggled aboard or out of the airport. They may seem a little harsh at times, but that’s just a part of the job. Nobody would take a smiling security agent very seriously.
