5 EUR (about $1 in 1975) is about the cost of a Döner Kebab which is more than enough for a teenager
You watched any teenage boys eating, recently?
I assume a doner is about the same as a gyro sandwich, around here (usually $7-$10).
A good teenager can shovel down two of them, easy.
Granted, there's less of a risk of traffic in the sky than on the Autobahn
