Wow! 125 Euro is huge, well I have almost the same experience during my vacation last year. As I return back here in Saudi Arabia, I paid 5,500Php for a PCR test that's for a rush result (12hrs). If you want the normal which the result will out after 24 hrs, you can have it for 4,500php but still expensive. They don't even consider if you are an OFW.
I already have my booster shot last Jan-19, and guess what, I have 3 different vaccines AstraZeneca, Pfizer and Moderna. I think I'm now a certified zombie lol.
Stay safe and healthy te.
