If you need it and are still looking for it? Are you really serious OP?
So if all you need is a virtual card to be used for online payment, can he do it even if he is not there in the UAE? Will the food be delivered to you personally? So you will also let him know your exact address as well as your Full name and contact details in case of need.
You should only deal with trusted members. Of course, you will give him the payment before he places the order or checks it out, the service fee must be included, so how much will you pay to the user who can do it?
The argument for needing bitcoin for food payment was vey vague and i was sure this was his scam attempt. I kept on following this thread to see if he
(OP) could come up with any genuine reason but he failed to do so and never returned to this thread.
