Eating and drinking are strictly prohibited on the BTS Skytrain (Bangkok's elevated rapid transit system) as well as within the "Paid Area" of the stations. This rule is rigorously enforced by security guards and station staff to maintain the high standard of cleanliness for which the system is famous. If you are caught consuming food or beverages, including small snacks or bubble tea, you will likely be approached by a guard and asked to stop immediately; repeat offenders or those causing a mess can face fines of up to 2,000 Baht. While you are allowed to carry food and drinks with you, they must be kept in sealed containers or bags; for example, if you buy a coffee at a station kiosk, you must finish it or place it in a carrier bag before passing through the ticket gates. This policy has successfully kept the trains free of litter, pests, and unpleasant odors, contributing to a more pleasant commuting environment for the millions of passengers who use the service daily. Most stations feature a variety of food stalls and convenience stores just outside the turnstiles, allowing travelers to eat their fill before they begin their journey or after they exit the paid zone.
