Debate is raging about whether or not it is acceptable for Arriva bus drivers to give out vouchers instead of change.
People using the buses in Leicestershire can expect to receive an IOU in the future if they do not have the correct change for their fare.
They can either be used for future travel or changed for cash at an Arriva travel shop within four weeks.
Arriva manager Steve Smith said: "This will ensure our driving team continue to provide excellent service to our customers and make bus travel even easier."
While some people think it is a good idea, others hate the thought of being denied change.
Ash Ali, 35, of Evington, Leicester, said: "I couldn't believe it when I read it in the Mercury.
"It's a ridiculous idea.
"If you pay someone more than something's worth they give you change - what if shops started doing it?
"Bus fares are expensive enough as it is. You don't want to be letting them keep some of your money until next time you use a bus."
Martin Crooks, 49, of Birstall, said: "I imagine a lot of people are going to lose their vouchers or forget to claim their money on time.
"But I can see that the bus company can't give its driver unlimited change."
Since the Mercury broke the story on Saturday our online readers have been adding their comments.
A reader called Volisios said: "They're doing this because they know there will be a fair percentage of these vouchers never redeemed - ie: free money for Arriva - Welcome to rip-off Britain once again."
Another reader, called Llamalamb, said UK bus companies should have a flat rate for all journeys so people knew what change they needed.
Ralph_T said: "I used to be a bus driver for First and it was suggested to the management that it would be an idea to increase the float from what we had, £5 to £10.
"The response was 'There are 300 drivers and if each driver had £10 that would be £3,000 of dead money that we cannot use'."
Reader Ford0 said: "This a stupid idea.
"The drivers never have change. Maybe the drivers should be given more change."

"It's good the bus drivers won't have to carry so much money. They don't want to have loads of change onboard so I think it's fair enough, really."
Jake Humber, 24, building society clerk, Leicester city centre
"It's wasteful to be printing all that stuff off and it's going to be a hassle for the bus passengers who want to redeem their vouchers."
Chloe Pettitt, 16, student, Scraptoft
"It's not a good idea. A lot of people will probably want the change for buying other things. And you don't want to be waiting for the money."
Zoe Stephenson, 23, student, Leicester city centre
"I think it's a good idea and safer for the bus drivers than carrying more money.
"I've spent a lot of time in Edinburgh where they just don't give change so you're always paying 20p more to travel."
Jake Scroby, 26, builder. Thurlaston
"If you use the bus a lot it won't matter because you can use the voucher the next time. But I only use buses occasionally so it would be a hassle for me if they gave me a voucher."
Joshua Pratt, 28, teacher. Market Harborough
"I guess if you hadn't got the right money and wanted to catch a bus you'd be fine with it. It's a way of making bus travel more accessible and easier for everyone."
