This means no sales, no themed merchandise, no decorations. December 25 and most other day are treated just like any other day for all stores malls, restaurants, ect.
You’d still get non religious holiday events like mothers days, or independence days.
What whould change?
Yeah I don’t necessarily buy a lot of things when I go out during christmas time, but the lights and decorations just add to the “christmas spirit” for me.
Do you live in a place with snow?
No.
