Ja maar hoeveel heb je nog 300 ofzo GAST 300?! Doe ff normaal

"Yes, but how many do you still have, around 300? 300?! Behave normally" Apologies, but the meaning of this text might be lost in translation a bit. However, the context appears to be that someone is asking another person about the quantity of a specific item that they have, suggesting it could be around 300. There's also an expression of shock or disbelief about this number. The person is then asked to behave normally. So based on this, to generate a most lifelike image, the text could be rephrased to: "A surprised person questioning another about their large collection, around 300 items, and asking them to calm down."
