T and I sometimes have treats together, but one of us will make the unilateral decision to bring something to the session, so we don't have to go through that awkward thing of offering, refusing etc. I understand about not having any money, but maybe there are creative ways you can contribute now and then? Recently Starbucks in the UK did a 2 for 1 voucher, so I brought drinks for me and T and when she thanked me I said "No worries- yours was free- really!" Or I'll sometimes bring cakes or biscuits for us if I've baked some.

I get it about not wanting to eat or drink in front of T. I think for me it was that there's something so pathetically HUMAN about it, and on some level I was ashamed of being human and didn't want it to be 'seen'. T eating and drinking with me has actually been very levelling and I'm sure it has helped me to talk about all kinds of bodily etc things which I didn't want previous Ts to know about me.
