I have a more powerful one to tell, i used to work at this club
at somewhere near dhoby ghaut, the name start with d one. Anyway,
the will recycle used mineral water bottles. The mineral water are
normally used by guests to mix with wine or quench thirst.
Means you drink finish the bottle of water then u go home already,
the SOP is to collect all the used bottles from the rooms, refill
the tap water DIRECTLY without washing into the bottle again just
hours before the club open for business. Once filled up again,
simply put it all back to the rooms with the cap on.
No seal is ok, because most customers will never check or they will
not be bothered to ask as they may feel troublesome or they may
think maybe just that bottled not sealed tightly.
Only the bottle of water in the room is recycle one, normally if
you request second bottle, it will be the original unopened one. In
doing so, when the customer see the bottle in unsealed, you can
simply say oh, it was a mistake, or the seal is just not tight for
this bottle, we replace for you.
There is alot of sneaky things in food and drinks business. It's
almost like magic show, alot of things done behind the
curtains.
