Is this what they mean by A la cart?

Did the food shop at M & S this morning, and then went for a coffee. There was a small queue waiting to be seated in the coffee shop, and a couple pushed in front of me as if I was invisible. I said, excuse me, I am in the queue, and they didn't budge.  I would usually argue my case, but I said, I was waiting here before you came along, but you can go in front of me. They didn't bat an eyelid, but the lady behind me said, it's a good job not everyone is like that. Filled up with petrol on the way home, then called in the library to collect three books I have ordered. After I had put the shopping away, I put the towels on the line, and not long afterwards the heavens opened. I got soaked, and had to change, and dry my hair. Maybe it's not my day.
