As long as they have adequate complimentary food and drinks in the club, I have no issue with having an additional vending machine to sell things for people to grab and go.
Whether I will use that vending machine will depends on whether it is comparable in price to those sold in concourse, or comparable in price in a hotel minibar. $3 for a 20 oz bottle of coke? No problem. $6 for that? I will pass.
