Free Coffee & Cake Voucher

This is not a whinge or anything, just a simple question. Perhaps someone from the centre could answer?

I took my free coffee and cake voucher to the visitor centre on Sunday. Now it was address to both me and my partner, and I read the voucher as being coffee and cake for the person(s) named on this card, as we are both members. The chappy at the coffee shop insisted it was one per transaction?

Was I right in my thinking? Or was the chappy behind the counter right? As I say, I don't want him getting into any trouble or anything, as he is always very friendly and helpful. It's just been nurdling in my brain since the weekend! ;o)
