If I make you breakfast in bed, a simple “Thank You” will suffice. None of this “How did you get in my house” business. So rude.
Oh my gosh people, be nice to your waiter/waitress, it’s not their fault that your food is cold or if it’s under cooked. Be nice to the cashiers who are still training and can’t ring up your items as quickly as you want. If a stranger smiles and says hello to you, smile and say hello back! It’s just common courtesy, I don’t understand why people have to be so rude.
