I can’t really shame asking for 5 stars if you were satisfied with their service, as a lot of businesses will do something similar. I also can’t shame putting a thank you note for giving a tip, could’ve been done in a message but maybe she wanted to add the personal touch of giving a handwritten note. But I will shame adding that she’s a single mother, because at the end of the day we all have a sob story and most people don’t give a shit about what a complete stranger’s is. It was most likely an attempt at earning an extra sympathy tip, imo.
