So taking that to (il)logical extremes - if I like my alcoholic beverages served in the skulls of my vanquished enemies by naked handmaidens then I should be able to demand it from any establishment I go into?
The answer to the above is that, yes, you can indeed request your beverage served any way you like it but that doesn't mean the establishment has to cater to you and if they are legally forbidden from doing so they would be somewhat foolhardy to ignore that.
//edit and the taste argument isn't one that I buy into very much, as I've mentioned I drank out of plastic glasses quite a lot (the hard polycarbonate type) and didn't notice much, if any, difference for average beers or lagers.
