Why don't they make paying toilets where you can have such services without the hassle of carrying stuff?
It's not a terrible idea to carry around tissues anyway.

People can be very disingenuous when they want to. So while requiring QR codes is ridiculous, they should note that normally you’re expected to have your own toilet paper because toilets aren’t stocked with it.
That's quite self-centred.
Secondly, giving that context requires the writer to know that it's not normal. If it's not normal. Yet you've failed to give that context. Your comment could just as easily be linked to in a forum mainly used by Hong Kongers or Singaporeans. Obviously, you have no reason to accommodate them because you shouldn't expect them to be your audience.
An analogy would be – someone from a non-tipping country complains about the fact that some restaurants in the US have a "compulsory gratuity" of 20% for larger parties. Sure, somewhat outrageous, but less so if you consider that tipping 15-20% is the norm in the US anyway.
