I definitely wait for the shower to warm up... But hell yeah drinking in the shower is great. I bring my morning coffee with me quite often. And something I'll get done working on something outside and crack a nice cold beer and head in the house and have a shower to clean up, bring my beer with me!
I took enjoy morning coffee or a cold beer in the shower. Have you ever had a delicious smoothie in the shower? I don't know why but the most enjoyable shower drink I ever had was a cold smoothie while washing off after a trip to the beach
