The number of liquor cabinets at 24 Sussex when JustinTrudeau became PM would reflect Harper's practices, not Trudeau's. I don't know how many liquor cabinets there are at Rideau Cottage, do you? Also, you don't need more than one cabinet, you just have to keep track of what was used for what purpose - that kind of thing is run on the honour system in the private sector too. I think it's also worth noting that JT doesn't drink very much anyway.
