As part of restaurant SOP to make everything clean and look shiny, the screen on touchscreen kiosks is wiped at least daily, and often several times a day. Being glass, sanitisers are easily used.

On the other hand, paper menus which are touched by dozens of customers every day are not even wiped, and possibly never ever sanitised. Paper, being porus, can absorb bacteria which can sometimes even thrive and grow.

So, if you order from a paper menu, please wash your hands AFTER ordering.

If ordering at the kiosk, go ahead and enjoy your food.
