I got hot water yesterday at lunch time along with my meal. The only beverage I had. My bill reflected $2.00 for hot water. The other two in my party got cold water. There was no charge for that.
Normal for a restaurant to charge for that cost. Other restaurants also charge plate fees.
I'm sure if you're just getting hot water, they won't charge you.
When we order tea, they charge for the water but that includes the tea.
