I like to drink water during my office work because I feel thirsty and for this, I have to permission from my boss to have some water but she doesn't like my act of going to drink water after a short time because my time waste, and I do not complete my work. So she suggested me, pack a water bottle in your bag before coming to the office, I implemented her suggestion and I feel comfortable now and my boss is also happy with me. By the way, Do you have any plans to go on a trip these days?
