Is it unreasonable to expect strangers (shop assistants, clients etc) to use my title and surname instead of my first name unless I say otherwise? I just cannot stand the rudeness of being called my first name by a bank worker, just for example, without reason. We are not friends or colleagues, there is no need. It is presumptuous and rude. Is there ever a polite way of asking someone not to? I rarely dare say anything especially to clients and yet I really don’t like it. Do others think this is fine?
