For us, of paramount importance when eating on public transit is that the food be easy to eat, quickly eaten, and of minimal disturbance to other passengers. These are the general guidelines we try to follow:
We think it's ok to eat...
• Small snacks, like granola bars, pretzels, or trail mix.
• Most fruits. These are easily and quickly eaten with one hand while hanging on to an overhead bar. Dealing with cores or peels can sometimes be a pain, though.
• Sandwiches. We don't normally go for whole meals on the bus, but sometimes it's an unfortunate necessity. In these cases, a ham and cheese sandwich is usually a better choice than a foot-long sub with all the toppings.
• Burritos. This can be an iffy one. While most burritos are self-contained and can be eaten very quickly, they also tend to have a strong aroma.
We think it's best to avoid...
• Anything requiring silverware. This just gets annoying for both you and the people around you. There's not a lot of room to maneuver on a bus or train and it's too easy to accidentally elbow your neighbor or drop food on the floor.
• Anything with excessive packaging. Again, this is more annoying to you than anything else, and it can also often intrude on other people's of personal space.
• Anything smelly. Leave the tuna sandwich for another day. Stick with foods that have very little aroma or with aromas that aren't likely to offend.
• Anything excessively crunchy. An apple is usually ok, but we think eating a big bag of chips can get disruptive to other passengers.
