Hi Majdi,
- Unless it's a well ventilated space, don't eat foods that smell strongly in the office (fish, curry, eggs etc).
- If you're in the office, be aware of signals that show someone might not want to be interrupted - headphones in, sitting separately from everyone else etc.
- If you're working remotely and need to speak to someone, drop them a message to check if they are free before calling.
- Be on time for meetings, and message if you are going to be late. British people are very punctual.
- Ask before you borrow things - even if it's just a pen.
- 'Please' and 'thank you' are really important to us Brits!
