Probably not Purple but I do know that the large coffee and muffin chain I referred to in an earlier post confirmed to me that they rectified the rate on the day I contacted them so they clearly had the skills.
I also have no doubt that the restaurant I was in today, as a major multinational, is very likely to have the skills - but if I am wrong I'll be happy to clarify when I get their response.
I do think however that there is a huge inertia when it comes to paying for goods and services. Most, if not all, of us have taken a hit in our incomes in some way or other and have had to tighten our belts and the €5+ in excess "VAT" that I paid in the examples I quoted does matter to me. So if finding it unacceptable that a large organisation continues to indicate its VAT rate at 13.5% makes me one of the "idiots" you refer to in your post Purple I'll happily wear the badge
If things are that tight it might be worth skipping the coffee and muffin.
