Even in good times the French are miserable unwelcoming barstewards, lately just got worse.
Can all Britts who holiday there have a year or two off, maybe soften them up for a fair debate. Even if feel need to cross the channel to France due to convenience, just drive through, spend the 1 night there maybe, on way to better places. There are plenty out there.
You never you know, you may find a holiday in Spain, Italy, Portugal, etc. More fun and the locals more welcoming.
