I never bump into this silly game in Asia. I have been disappointed a couple of times, some time ago now, at SYD where we were barred entry to Glass for breaky and redirected to the EL instead - never once seen these silly shenanigans in any Asian hotel.
Seems to be standard now in Australia which still baffles me. Trying to squeeze another $10-20 for something that costs the hotel virtually nothing, let alone the hassle trying to police the buffet selection.
