Penha

You might be forgiven for thinking this is LIXO buslines. But I think lixo means "rubbish" in Portuguese (please correct me if I'm wrong). Not a good name for an bus company.

This large plastic bag can double as a shopping bag if you're not feeling sick. It also features a phone number (linha direta 0800-99-2323) in case you need to order another bag. Unlike on planes, you are allowed to use your mobile phone while aboard a bus. Just don't distract the pilot.

"Environmentally friendly", says this bag in German. "This polyethylene bag is produced in an environmentally friendly manner, burns non-toxically, and is groundwater-neutral and recyclable."

Seems almost a shame to use it to hold all those nasty toxic stomach contents.

PolskiExpress

A paper bag from a firm whose buses ply Poland.

P.W. Jones Coaches

Another bag that features poetry: "Phil's Fleet we're hard to beat." (See Cyprus Airways for another.) It's also packed with useful instructions: "Please use this bag for used cartons, wrappings, waste paper, empty cans, etc., or in case of travel sickness. When full please ask your driver for a replacement. Thank you for helping to keep your Coach tidy and pleasant." And odour-free, we might add.

Coachsick passengers will have to travel a long way before they fill up this bag: Phil reportedly drives carefully, and the bag is a roomy 35.8 x 24.6 cm.

This gem was stolen from a coach in Herefordshire, in the west of England.

P.W. Jones Coaches (no stripe)

No stripe on the top left of this bag. You're still supposed to fill it up before handing it in for another.

Rápido Ribeirão Preto

A Brazilian busbag festooned with phone numbers to call if you want to buy a ticket. One would have thought you would already have a ticket if you have this bag in your possession.

Reunidas/REAL

My Portuguese is pretty non-existent, but I think this bag tells you, "in case of necessity, call the motorist".
