Movin' On - Beer on sale

We usually lunch at a golf course. It's quiet. It's on a golf course. We like the environment.
When the weather is lousy - we look elsewhere.
On "resort road" we find a good pub. In fact one day they were selling everything at half price. All the beer and all the "appies" (appetizers) at half price.
"Oh yes, every Wednesday we sell everything here in the pub at half price".
The other day we can't find a golf course that isn't booked so I say "Hey, it's Wednesday! Let's go for lunch!"
Things are pretty quiet at first. We get a good table, the US Open is on the TV, we order the beer and "appies" - 2 orders of the expensive prawns.
People suddenly start pouring into this little pub! Chairs moving around. People talking tennis. People waving "Hey Bob, over here! we'll find a chair!" Seems every time I look away from my tennis game, another 2 couples are walking in.
The kitchen appears every once in a while with "watch it - it's hot! dishes" but none of them are ours.
It happens again. "Who ordered the chicken wings? Okay sir, here's the first, we've bringing the second order right away".
We're not happy.
"Yes sir - very sorry - what was your order? Mussels? They're on their way".
"No, we ordered the prawns".
"Ah yes, right away, sir".
People are looking for a place to sit, new girls are appearing to wait on the tables, "frantic" is not too strong a word.
The kitchen arrives with our food. Shrimp and mussels. We don't say a word. We are happy. The chicken wings table even cheers when we get our food. And it's good. We love the mussels especially, and we're glad they made a mistake.
"The beer is free" she says, "I'm sorry for the long wait".
The bill was $8 !!!!!
