Thai not ready for prime time

It's about 3:00 p.m., the sun is beating down, it's hot. The menu is outside and the phone number posted on the window. After looking over the menu, I was ready to order, so I tried calling, the phone is busy. I see the door is open, so I go inside. The lady inside, walks to the middle of the room, tells me to call, I told her I tried to call and the line was busy.  I ordered the Pad See Ew and the lady disappeared into the kitchen.
