I read in my student book a texte about the "Debrett's gGuide to mMobile pPhone eEtiquette" and onthere is one piece of the advices that is particularly good infrom my point of view: when wyou are talking in your office with somebody and thaten suddenly anyasomeone rings you on your phone, please, don't answer, keep talking with your colleague.

I personally would use “call” instead of “ring” but I left it since I think it is common in the UK.

Of course, you can shorten the first conversation, and apologize .

The personne who tries to jointerrupt you don'esn’t deserve any kind of priority unless, unfortunetly ifately, you are a fireman.

Another piece of advice is to respect the quiet zones on the train, plane, bus... Byand bus. From my little experience, iI can say that the people respect these areas when they are on the train for a long trip , probably because on the train we can find good well identified quiet zones, but on the bus, tramway and onfor short distances, there are always, or more exactly very often, some people who call , speak on , or sometimes, theeven worste, shout on their phones.

“there are always, or more exactly very often, some people who“ this sentence feels awkward to me. I would just write “there are often people who“ to keep it concise

Edited the last part of the sentence to eliminate redundancy

Are these bus'es’ phone travellers all deaf ?
