This travel tip brought to you by Bari Brenner of the Bay Area: I am going to be your mom right now and tell you what she did (I hope), about proper behavior in public that applies to both when you’re traveling and all other times: MIND YOUR MANNERS!

This comes from a conversation I recently had with a freelance travel writer (who wants to remain anonymous), who confessed she’s thinking about not traveling at all anymore.

The incident that brought her to this semi-decision happened on a trip to Cambodia. She was seated on the plane between an overweight man and another who — there’s no way to say this delicately —”picked his nose the whole time” and kept touching her as he spoke, to emphasize conversation points. (She had no room to lean away from the finger-pointer.) It was a full flight, and there was nowhere she could move.

After her pleasant stay in Cambodia, she boarded the plane to go home, suddenly remembered the tortuous seatmate she’d endured coming over, sat down and burst into tears.

Fortunately, a compassionate flight attendant immediately moved her to an aisle where she could be alone and she calmed down.

Manners, people, manners. Tip: They matter.
