It wouldn't even occur to me; I can't take big gulps of scalding hot liquids, certainly not enough to wash down a couple of big pills. Does anyone do this? I'm genuinely curious, as the thought of it makes me cringe. Maybe I'm just weird or have a particularly heat-sensitive mouth

Regardless, the issue at hand, as it relates to the thread, is that a cup of tap water seems like a reasonable thing for a paying customer to ask for without charge.
