Denied purchase access to CDG 2F Air France Lounge

Data point that will hopefully help someone. Most of the posts online suggested paid entry to the lounge here was possible.

Had a layover to connecting flight out of 2F on a Saturday. We were told no purchase entry to the AF lounge all day, even during quieter periods, "because in 1 hour it will be busy again."

So for those in similar situation, would purchase access ahead of time if given the option on AF website.
