One of the best profit generators for high-end restaurants is bottled water – they come in two types.
This makes it easy for waiters to ask ‘still’ or ‘sparking?’ And it becomes hard for you to say just ‘tap water’.
And I find that almost every café or restaurant in Bangkok seem to take this further. Sorry, no tap water. We only serve bottled water.
It generates profit but it’s also a contributor to plastic pollution.
p.s. And why do we find it hard to just say tap water? That’s because we are highly sociable creatures. Nobody enjoys looking silly or cheap, especially when dining in a high-end restaurant.
