RyanAir's business model is hyper-aggressive penny-pinching on basically everything that allows pinching pennies. The costs are so high because they want to really really disincentive people from using staff for this kind of thing, so on average they won't have to hire as much staff. This is one reason why some RyanAir flights can be as low as €20 (whereas e.g. KLM is €200 for a similar or identical flight). On bigger airports it's not a huge problem because you can typically use the machines, which are free.
