Language mixups

The other day I went through the self scan line because I only had one thing, it was early in the morning, and I didn't want to try to speak other languages. But I accidentally scanned my potiron (pumpkin) twice, so I had to ask for help anyway. When the lady came over I heard my internal voice say:"il y a zwei ici, aber tengo solo uno". (French, German, French, German, then Spanish for those who don't recognize the languages). So I just spoke to the nice lady in English. What a mashup! I am definitely having trouble with language compartments in my head being extremely porous (nonexistent?)
