This is exactly as it was received...
"goodmorning dear customer i am regret to inform you your optician oppt been cancelled today please call to rebook sorry for inconveniece caused thank you"
No caps, no punctuation at all. Dodgy spelling and grammar.
Obviously it satisfactorily conveys its intended message so AIBU to think that this sort of lazy texting is not appropriate for a business communication? Or am I just an old fogey, unnecessarily hung up on outdated use of English?
