Nankai South Tower Hotel

Luxurious blue plastic bag with a hole so you can hang it up after use.

Nappy bag

That's "diaper bag" for our American cousins.

Mark Brace said this was perfumed. Not by the time it reached me, it wasn't. At least it was empty, and appeared to be reasonably clean.

No, I am not going to start collecting these!

nap sack

With a vase of flowers where you can conceal the bag if there's no bin available.

No idea what that has to do with napping, though.

There's also the enigmatic "pull tab" on the base: a novel dispensing mode, perhaps?

nap sack (no pull tab)

The "pull tab" instruction on the reverse clearly outlived its usefulness, and has been pulled.

Necessities®

A surfeit of euphemisms: this "Courtesy Bag" is "for your needs away from home".

It's only when you flip it over that you realize what it's really for: "Please use this bag for disposal", it says. "A bio-degradable recyclable paper product".

So it's to dispose of some kind of waste... and at 7.6 x 18.2 cm, it's not big enough to be a barfbag or to hold maxi-pads. Ergo, it must be a sanibag, designed specifically for tampons or smaller sanitary napkins.

Notre-Bel

Cartoon of a boy and a girl clearing up the mess after someone failed to use this bag. Text is in English and Thai.

Novotel

This hotel bag features a frightening-looking triangle with no less than six wiggly arrows coming out of it. All inside a roadsign.

Novotel Bangkok Airport

Fancy silver box conceals a boring plain white bag.
