I particularly liked the 'may' in 'candles may be used'. Like they aren't sure yet whether there will be a call for them or not, they just want to keep the option open.

Maybe it's a marketing ploy. They're starting out small this time, but next time it'll be 'elephants may be used', and then when the place it packed, they'll announce, "Oh, sorry, no, we decided in the end we didn't need them."
