Sandwich

"Sandwich" to me is a very narrow definition.

  • When you go to the sandwich isle of Tesco for a meal deal, you expect things like BLT, tuna mayo, cheese triple. You don't expect there to be a roll, a burger, a taco, a baguette, or a hot dog. Those will be in their own section.
  • When you go to Split airport in Croatia, and they close the majority of shops at night time with only one stall left open, all they advertise they are selling is "sandwiches". And they only 2 options: chicken, or cheese.
  • When there's an announcement on a GWR train saying the cart is coming through selling "sandwiches, crisps, soft drinks, tea and coffee", I'm not expecting them to have a hot dog.
  • When I look at a local indie artisan coffee shop brunch menu, and look under the section for sandwiches, hot dog isn't under there, hot dog is in its own section, if at all.
  • If you go on Family Fortunes, and you're asked to name sandwiches from a survey of 100 people, the top result is probably BLT.
  • If you look for emojis of sandwiches, none of them are hot dogs.


Sandwich has a specific structure, and there is an expected, small subset of predictable sandwiches.

Not a sandwich:

  • Chip butty, despite having the structure of a sandwich, has its own name, and does not fall into the category of predictable sandwiches.
  • Ice cream sandwich throws a spanner to this: it's not a predictable sandwich, so it's not a type of sandwich, but, it does borrow the sandwich only by name and structure. 
  • A sub, wrap, or burrito might appear in a certain subsection of the Tesco meal deal area next to sandwiches, but because they have a different structure and their own name, they aren't sandwiches - even if they have predictable fillings.


When we say sandwich without context, we mean a subset with predictable structure and fillings.

How to use an airport

Pre-req:

  • Passport (not expiring within 6 months)
  • Booked tickets and boarding pass loaded to phone

  • Travel insurance
  • Online check-in completed as early as possible, not at the last minute 
  • If driving, book parking
  • Data roaming planned 
  • Check for required vaccinations on government travel advice

  • Generally, no liquids over 100ml or pressured cans
  • Cabin luggage (backpack, small suitcase etc)

Steps:

  1. Regularly check the gate and departure time on display boards for cancellations

  5. Go through the shopping labyrinth to the gate waiting lounge
  6. Wait until your gate is announced then go to gate. Buy snacks or drink for the plane.
  7. Scan boarding pass and board the plane (may involve a bus, corridors, waiting rooms, walking outside) 
  8. Find seat, ignore anyone who asks to swap a seat with you
  9. Follow instructions. Get up at least once an hour or two either for toilet or water or chat, it really helps with anxiety.
  10. Leave plane, double check you have everything e.g. headphones, passport, overhead bags 
  11. Arrivals - Passport stamp, customs bags checks if required
  12. Collect luggage from the right conveyor for your flight
