Yes, we'd all like our beers served at an appropriate temperature, in the appropriate glass, but sometimes you have to make do.
My local hasn't the space of a super pub to have a dedicated cellar temp fridge, so everything is either from the cooler or the shelf. If the shelf is too warm, then a bottle from the cooler, when half way through the previous one gives it a chance to warm up nicely. It's not rocket science.
But yes, being offered a bottle and [i:2b8b67nc]no [/i:2b8b67nc]glass is just rude.
