Regarding the HSR…
Don’t do it! Even though the regs say you can eat, I’m on the HSR right now and they just announced no eating or drinking on the train. The attendants have also been suspiciously eyeing the Starbucks carry out bag sitting on my seat tray each time they walk by, as if they’re waiting to pounce on me. I don’t dare until I get to Taichung.
EDIT: I wonder now if the English is wrong in the regulation. Perhaps they mean eating is permitted in train stations, not in the trains themselves.
