Self service

Self-service is when you do things all by yourself, without needing anyone else's help. Imagine you go to a restaurant and instead of telling the waiter what you want to eat, you get to pick your own food from a buffet. That's self-service! You get to choose what you want to eat and how much you want to eat. You also get to fill up your own cup with drinks using a machine, and take your own napkins and utensils. It's like being your own boss of picking and choosing without bothering anyone else.

Another example of self-service is using an ATM machine. When you have money in your bank account and you want to take some cash out for yourself, you don't need to wait in a line and talk to a bank teller. Instead, you can go to an ATM machine, insert your bank card, follow the instructions on the screen, and take out the amount of money you need all by yourself. It saves you time and effort.

Self-service is when you take care of yourself and do things on your own without relying on someone else. It can make things faster, easier, and more convenient.
