I have been working as a part-time waitress in one of restaurant near my university for 5 months. I honestly think that working with human is the most difficult thing, they obviously have brains but sometimes their acts show otherwise. Sometimes, they make my day brighter but sometimes they make my whole day disaster. As you can see above, the coins are actually the tips that I got when I worked and hopefully I will earn more. Thank you my dear customers and keep giving me more tips!!!
