No one eats on the Beijing subway anyway. Some context for non-China subway readers: Compared to NA/EU, staffing is very high. All bags must go through x-ray scanners when entering any station. Any bottle of water is suspect and needs a sip from, a trusting nod from security (like: supermarket shopping) or to be discarded. 2-4 security staff and an x-ray machine or two are at any entrance to a ticket hall at all subway stations. I've never seen someone chomp down a hamburger or jianbing when going through an entrance. I've actually never seen someone eat on a train on daily subway commutes in Beijing, Shanghai yes but not a lot and not in rush hour. Beijing subway also has an 'attendant' (someone in uniformed black with an arm band, not police, just 'security') for every 2-3 carriages of every train going through 'downtown' (not sure Beijing has a downtown, but within the 3rd rind road). Other China subways don't have this, it's a Beijing thing.
