Yes I could really feel the social anxiety coming through in the article. One thing that someone told me that really helped is that everyone is trying to help you by telling you what you should do. So if they ask to take your coat, say yes. They're telling you that it's not appropriate to keep it on the back of your chair. If they ask you if you want to wait at the bar, say yes. Basically, just keep saying yes. At this kind of place they aren't out to get you by sneaking in an extra charge for something (I could also feel her concern there). If it does involve money, like choosing a wine, you can also just ask for some advice. "What would you recommend around £30?" The staff aren't going to judge you - or if they are they'll have a whole new round of folk to judge tomorrow and won't remember your face.
