Male General Manager to Female Team Leader

At a budget meeting with other managers + accountants (only female in attendance), the meeting is going to take longer than expected. Out of the blue my boss turns to me and asks if I will take his credit card and pop down to the cafe to buy everyone sandwiches. Apparently I don't need to be present for the next discussion....I return with the food. There is much gushing over what a fantastic job I did (it's fucking sandwiches??!!) and jokes about whether i used the company credit card to buy new shoes.
