many people eat lunch at work, or in a lunch room, break room, car etc…
when you eat, make it something wonderful.
use a plate (not paper)
use a real fork/spoon (not plastic)
use a real glass
use a real napkin
Have the items with you and at lunch time, take it out and make it a grand occasion. Enjoy your lunch. Chew slowly. Taste the food. Some even put their fork down in between bites. Some take a small sip. There is nothing wrong with plastic spoons/paper plates, but make it special for you. Enjoy your hour or whatever time you are permitted.
