What should I do? I bumped my drink and spilled grape juice all over the laptop
How did you spill your drink on your laptop?
I lifted the laptop without taking care of my surroundings.
I know you do not like it when you spilled your drink on your laptop but accidents do happen. You should not get down on yourself over this.
I will blame the restaurant for not being careful with the drinks
It's not okay to blame the restaurant for your mishap. Take responsibility for your own actions but don't be too upset about it. It was an accident.
