Often of a morning i like to fill up my refillable Waitrose cup with the free coffee which I drink when wandering around the shop and picking up shopping that qualifies said free drink.
It has recently been raised by the veh naice security guard that I need to prove i have paid for it before getting it. I always thought that so long as I had paid for my shopping (ergo accounting for free coffee which would also be in the receipt) & I had not left premises without paying nor intentionally depriving them. first world problem i know! but AIBU?
