Single-use raincoats

You can find single-use-plastic raincoats for less than $1 online. You often see them for sale at concerts or other outdoor events and when it's time to leave, they're littered on the ground in masses. They are marketed as "a disposable raincoat, lightweight and convenient to use. One size fits all. A must for sudden rain, sports/music events, travel, camping, walking, concerts, outdoor events etc. Can be folded to be a very small size, easily stored."
What are your thoughts on these raincoats? Personally, we think it's pretty easy to bring a reusable rain coat with you. We hope that your event will never sell or provide these at your events.
