“Americans would have loved proper British fish and chips!”
Yeah good job you’re not running a fucking restaurant pal, with your infantile level of international market comprehension amounting to “well I like it, so therefore everyone else will!”. It’s called tailoring to the national market that you’re serving to, you dense fuck.
And no, gravy is not a staple accompaniment to fish and chips in the UK. 🤮 Even curry sauce is only a relatively recent introduction, and is not particularly traditional here.
