Oops I did it again!

Location: A supposedly swanky beauty parlour
Situation: Me after repeated calls fail to get a reservation. So I decide to walk in and pretend I have a reservation.

I open the door confidently on a Friday, late afternoon time slot.
Ugly looking and snooty parlour lady: Yes, can I help you?
Me (hesitating): I need a hair cut.
Her: Do u have a booking?
Me (boldly): Yeah.
Her (with a weird look on her face that I can not decipher): When did you call?
Me (after thinking a lot but pretending otherwise): In the morning.
her: What time was that?
Me (again rigorous thinking): Around 11 or 11.30 (I know that’s a safe time and I had spoken with her the same time day before yesterday)
Her (with some horrendous satirical expression): We were closed that time. Today I opened the parlour at 3 PM.
Many faces turn around and look at me. I resist turning around to look at them.
Me (stumped and hugely embarrassed but determined not to show it): Oh, is it? But I did call at that time and spoke with someone.
Her (with the 'I have won' expression): Just not possible.
Me (forcing a smile): Okay, but err and err… so… can I get a hair-cut?
Her: Sure.
I start walking towards the sofa with a clumsy smile.
Her: Not today. We are too busy.
Me (almost pleading): Its urgent. I have to attend a wedding. I can wait for you to finish other assignments.
Her (with an irritatingly disgusting expression): No, not today. You can come tomorrow or on Tuesday.
Me (struggling for words): But… it… it will be too late… I needed it for this weekend?
Ugly looking and snooty parlour lady says nothing.
I say nothing.
The many faces keep looking at me. I turn around and walk to the door and leave.
