Tesco rip off!

Sorry, but I need to vent!!
I went shopping at the Tesco today and I noticed this woman was staring at me in the same aisle I was in, no biggie...I moved to the next aisle and here she comes again...STARING!!
So now I'm like, what is her problem?? I finish up my shopping and head to the check out...of course who is there ahead of me, this same woman.
She turns around and starts staring again. So I start playing with my phone so I don't have to look at her.
Finally she says "I want to apologise for staring at you, but you look just like my daughter who just passed away." I felt really bad after that and gave her my condolences. She says "Thank you...but I have a favour to ask. I know it's weird and understand if you don't want to, but can you give me a hug and say 'Bye Mum to me?" Inside I was like Really?!??!, but understanding grief the way that I do, I went ahead and did it. She smiles, thanks me, and leaves. The cashier scans my stuff and the total comes out to £100.87 I knew something wasn't right, because it should have been like £20 or so. The cashier then tells me that my total was included with my mum's, I'm like, "What?!!!" She said, "Your mum said you were paying for her last few items along with your things. I told her that the woman was most definitely NOT my mum. She said, well I saw you hug her and heard you call her mum. I'm like OH MY I flew out of the store looking for this women, ready to get her! I see her loading up her car! She saw me and jumped in her car, I got to her as she was putting her leg in, and I started pulling her leg hard enough that her wooden leg came off!! So I grabbed her other leg and started pulling!! ...Just like I'm pulling yours right now! Hahaha!

Sorry! Tickled me on Facebook.
