Low likelihood ≠ "what if" any more or less than "high likelihood" = "what if". I am speaking from experience of what I've witnessed repeatedly at grocery stores in different countries when it comes to shopping with luggage in tow after trips by air and rail. You aren't forced to consider the likelihood of something hitting others who aren't you, but it's something that I do have to consider and that I shared here for the benefit of others.

I travel very often internationally, and I am about as much the proverbial cabin-baggage-only traveler as anyone else that travels a lot. It's not rare for me to arrive into airports or train stations in Europe or the Americas with cabin baggage-only, then hitting the grocery stores with my cabin baggage and come out of the store with 4 to 5 bags full of groceries. Why do that? Because I and my travel party members may be heading onward to somewhere where it's not sure when next it will be as convenient to get to the grocery stores of choice.
