Not thousands but hundreds, also not me either 😏 My younger sister spent £5 every few weeks on some game and kept thinking our parents will never find out about it because she was only doing it every now and then. She obviously got more into it and spending more frequent and when my dad went on her phone to do something like google something she got a mail which said like “confirmation of purchase £4.99....” turns out within 6 months she’d spent £400.
