Its funny you should mention this, I dont need to search for this because I already have an answer already, and you shouldn't really use wikipedia to find out what the law is, its not classed as a reliable source!!

I once got refuse onto the bus because I wanted to pay in change instead of paying with a £10 note, mainly for the bus drivers convenience rather than my own. He showed me up in front of the passengers, and this was a morning service that was full, and made a fuss for about 10 minutes about it.

I complained (being the dragon that I am) to Lancashire United and they said that this kind of policy was an old one, and they used to be able to accept no more than 21pence (or 23, cant quite recall the exact silly number) and I wanted to pay 30 pence.

His manager apologised though and said this kind of policy is just old fashioned, and bear in mind POLICY, not law, and they no longer use it. Any place that still uses this kind of policy is a bit rare to come by, and I dont see why they shouldnt take you're money for carrier bags as they're the price of coppers anyway, so if they start showing you up, simply complain loudly about them not accepting the value of the customers money and demand to speak to their superviser/manager, they'll soon accept your money, which is what I had to do to get on the bus!
