Is it more acceptable to say
"Please notice that smoking is prohibited in the office, coffee lounge, terrace and eating lunch in the offices is prohibited either"
instead of saying
"Please notice that smoking is prohibited in the office, coffee lounge and terrace and that all the employees cannot eat lunch in the offices either"?
Both are pretty awful.
Please note: No smoking in the office, coffee lounge or terrace. No food in the office areas. Thank you.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
