Sooo bad Lady M @ Sumerset

I've had a good day since I lived in Singapore. But today I got angry at Lady M.
I asked a waitress to bring my bill, but she told me " Pay at Casher". So I went to Cashier without receipt. There was long que at the Cashier, the clerk asked me to give the receipt, but I couldn't. I told her, I didn't get a receipt and I already ate. Unbelievably she said, I don't understand you. And she checked out next customer! Another clerk came up to me, and she made my receipt immediately. After that she asked the clerk at Cashier to check out me. But she left me until later.
まじでむかつく、、、
I must to do
• Get a receipt before paying
• Learn how to tell the complaint
• Never go to Lady M
