This is disgusting

So my husband has a habit of peeing in his beer cans when he drinks because he is too lazy to go upstairs to the bathroom. The other night he drunk a beer upstairs in bed and I woke up to him peeing in the can when there is a bathroom upstairs I’m so disgusted and turned off by this. I’m not sure what to do about it I throw the beer cans away but he usually drink at least a beer a day so it’s hard to keep up on them. He doesn’t have a bladder issue he just does it out of pure laziness what should I do?
