Paying the full balance for Christmas dining

[amispeakingintongues]

Anyone had to do this before?
I've already paid a £70 deposit at £10 per head but now they want the full balance (2 weeks before our booking) and it's rubbing me up the wrong way.

Since when did this become a thing, or have i been living under a rock?

Oops, I thought OP was referring to Xmas day, not a pre-Christmas meal. It’s a similar principle for pre-Christmas dining, though, particularly on weekend evenings.
