Today, I was in a nice coffee shop to get a flat white to take away. I've been in this place before, with no issue. The (nice) barista pushed the card machine towards me, and said 'if you'd just like to add a tip then here are the options' there was a list of tip amounts from 5% up to 30% with 'no tip' as the bottom option. I was a little nonplussed so I added 10%, but I really thought that it was a bit cheeky. The coffee was expensive enough as it was, should staff really be soliciting tips for takeaway coffee? One doesn't tip McDonald's staff, so why is coffee the exception?
