I've come across a phrase in the context of How to Split a Restaurant Bill with Friends While You Are With a Skint, which was written on March 15th 2015 by Liz Smith for The Debrief:
On this note, you should also be wary of the man who asks for some seasonal greens and a chips for the table. ‘For the Table’ means ‘I’m craving chips but I’m taking everyone down with me’.
You need to have stated your intentions for the chips at the time of ordering. As in, loudly saying, ‘I’m OK for chips’ to verbally state that you will not be entering into the chip contract. Don’t feel pressured.
I never saw "I'm okay for chips" before. Do you say that when you don't feel like something?
