This gets me. Some seemingly plural words, don't have a singular in the same context. The plural and singular are the same, even though ending in an "s". Goods, meaning things, is singular and plural. You can't have one "good"! The same for premises, meaning a building. There is no "premise" meaning a single building. A 'premise' is something completely different! And yes, I have seen the word 'premise' used to mean one building. This is from the Qantas web site. I was catching up on taking lithium batteries and power-banks in carry-on. I would hope it is a typo?
