I know this is a petty first world problem, but I'd like to make an offer to all baristas right here right now. I won't pour the top of my coffee into your trash can if you actually leave room for cream (which is why I presume you even ask this question in the first place). You can make overblown sounds of exasperation like I just riverdanced on your mom's taint as you did today when I poured a measly 1/4inch into the trash, but leaving a sliver as big as a piece of angelhair pasta around the lip of my cup does not "room for cream" make. Leaving room for cream has to be the easiest part of your job, how is this even happening?
