Sing it woman!

Another one for the books! I have a coworker who is from the Philippines and her accent is very strong. On Wednesday night, a lady comes in and my coworker goes anywhere ma'am! The lady with a sassy attitude, "well the sign says please wait to be seated" and my coworker goes yes but you can sit anywhere. Already I can tell this is going to be one heck of a customer. My coworker goes up to her and goes, "hello ma'am what can I get for you?" The lady says, "How is the hamburger steak made?" and my coworker goes we cook it well done and the lady interrupts her and says, "WELL I WANT IT RARE!" She goes okay ma'am we can do that. She then asks what she wants with her hamburger steak  and she says she wants potatoes and toss salad. My coworker then brings out her toss salad and she eats it. When my coworker brings out her hamburger steak she's crying. We have no idea why she's crying and she doesn't ask. She takes one bite of the hamburger steak and then takes a menu from another table and then pushes the plate away from her. She calls my coworker over and says I said I wanted a hamburger steak and she goes you know a hamburger steak like from McDonalds! (LADY THAT'S A HAMBURGER!) My poor coworker goes back to get her her hamburger. She and another table (which was coincidently my mom and brother) are the only people eating in the restaurant. I was sitting down with them since I had no other customers and all of a sudden the lady starts singing along to the radio that's playing in the dining area. Adele was playing. She literally starts singing along, "I HEARD THAT YOU....SETTLED DOWN...THAT YOU...FOUND A GIRL..."She literally sang her heart out like no one else was in the restuarant. My mom, brother, and I tried so hard to hold in our laughter. I honestly think she was crazy or something.
