So you're telling us that everyone else in the shop who surrounded her (including the woman who first came to her help) don't speak French????! And you believe those locals can't tell a foreign accent from a local one or recall seeing the pixelated Black man in the CCTV footage????!
uh huh your "logic" and one hell of a trip you're on.
As to the rest of your pathetic excuse making and logic, your French friends suddenly can't speak French or tell a foreigner from a local/regular just because you've decided you can't.
No wonder they're falling off their chairs from your repeated stupidity.
Good luck with the rest of your Can-can't performance - break a leg!
