I made a longer trip today and found that gas price thing does not always work as supposed.
No, these prices are not OK. Our gas price is usually in €1.2—1.4 range. So, I pressed [No] and entered right prices but could not update them
I thought that this happened because I clicked "98 regular" but didn't enter that. In next Gas station there was no gas prices yet and I entered both but got the same invalid error:
All other 10-20 gas stations I passed today were okay.
