My problem with afternoon tea is the sandwich fillings. Mayo with tuna, mustard with the ham, pickle with the cheese. I don't mind pickle but there's always too much in pre-packed sandwiches. Maybe it's a personal things but I don't like creamy fillings so I'm always SOL when it comes to BA sandwiches
Some more variety would be nice e.g. Cucumber and mint sandwhiches or smoked salmon. A bit more salad would be good too.
