“bring us some sandwiches” sounds most natural. Or “bring our members some sandwiches” if Saito is not eating.
yes… unless there is just one of each, in which case it is 'a vegetable sandwich (do you mean salad sandwich?), an Amercian club etc…"
It’s not necessary, but it’s not wrong. it would be ok if spoken, just to show that this is the last activity that you intend to do. Some people will tell you that you shouldn’t start a sentence with ‘and’ so be aware.
Hmm, either is ok. "How long will it take’ refers to the process of getting the rooms ready, “how soon will they be ready” refers to teh rooms themselves, but the meaning is the same and is clear in both questions.
If you have the questions "how long will it take, then ‘up to half an hour’ would fit best. If you ask ‘How soon will they be ready’ then ‘within half an hour is fine’. If you say just ‘half an hour’ then it will take about 30 minutes, if you say up to or within half an hour, you are suggesting that it will take 30 minutes at the most. Both are correct, but the meaning is slightly different.
Personally I wouldn’t use a hyphen (-) with euro or cent there, but as neither of those are the standard unit of currency in the UK, I may be wrong not to do so.
Either version is fine.
It gives a clearer reason as to why they cannot eat in the restaurant, so I agree you should change it.
I’d prefer ‘they’, yes. more than one meal.
All in coins please. I’d appreciate it if you could make it withinclude some one-euro coins and some 50-cent coins in the change.
Please givedeliver two servings of the sandwiches and coffee to each double room, and one serving to each single room. (Don’t forget that most hotels have coffee making facilities in the room, so you might want to indicate the difference between that instant coffee and the room service coffee by saying ‘sandwiches and fresh-ground coffee’)
