I am a few seats further back on the return leg of this journey in aisle seat 11D. Same plane (Boeing 767-800), seats, service and snack (which I decline when offered).
For some reason there seems to be a bit more leg room but that is probably because I am so tired I sleep for most of the 2+ hour flight and don’t realize the lack of legroom.
As we are taking off I ‘break the rules’ and devour a smoked chicken whole wheat sandwich from the airport Starbucks and the remaining two macaroons I received from the hotel the previous evening. Apparently bringing onboard outside food is banned on Thai LionAir so I figure the easiest way to eat it without being caught is during takeoff when all flight attendants are strapped to their seats. 
It works.
