oh dear Georgealbert, it was good that the fire brigade acted with full evacuation procedure's in place, if it was real building fire it could be disastrous.
It really annoys me to see Thais & Foreigners smoking on balconies and casually throwing the butt over the railing ... I've seen this dozens of times over the years, there should be stricter fines and warn folks when checking into hotels.
Same as at the Chatuchak markets, I see foreigner's walking around smoking, one time an older couple of Italians were puffing away on a cigarette and when they passed me I told them to put it out as they will be fined, they didn't care ... and just kept walking.
