Snobbish Cheapskate

Okay... the title may seem "unequal"
I mean.... how can you be snobbish and a cheapskate at the same time ?

So.............
One fine Sunday
Restaurant was crowded
A couple and their family at this table asked for the bill
then the couple came to the cashier to pay
they walked towards us with a hateful frown on their face, yes a hateful frown while we sat there smiling.

So the husband said
"This Restaurant is so expensive, I've never been to such an expensive restaurant, this is like a trap"
while the wife gave us the evil look
me and my mom looked at each other with the "huh?" look
I mean, come on man, we sell mineral water for half the price at what they sell at McDonald's or any other fast food restaurants. If he's never been to a restaurant "this" expensive, then he's never been to a restaurant at all, hey, he probably will yell at a fast food resto for selling fries at such a price.
Then my mum said politely "well, sir, the price is there on the menu"
He replied snobbishly "I never bother to look at the price on the menu, I don't care much about them"
then he continued "This is unbelievable, outrageous price, I'll never return here again"

We couldn't say anything at all at that time
what ? apologize ?
What should we apologize about ?
If you think that our price is too high, then don't eat here
Don't eat and get angry at us after you're done eating
The price is clearly printed on the menu, read it !!!
We just processed the bill and He paid, still with that ugly frown on his face
and we said thank you.
and we're actually glad that he said he'd never returned again.

So that you know, we always put our price on the menu, we ourselves don't like it when we go to a restaurant where the price is not on the menu, we don't like that !!
and we don't want to treat our guests that way, we want them to know our price before ordering !!!
Even so...... they get pissed at you....... oh my.... some people

and guess what ?
While he paid, his wife approached another table and said "Watch out eating here, they're expensive and they trick you with the prices"
The guests at that other table didn't respond, probably afraid of this old cranky creepy lady jabbering away.

So they left soon after.
Crazy family huh ?
Their whole family (6 of them) sat for almost 3 hours and only spend around US$40 and they hate us for it.
I mean..... Have they actually ever been to a restaurant ?
They've probably never been to a mall either
A cinema ? what's dat ? $5 for a ticket ? that's outrageous !!
They'll probably yell when they have to pay for kid's school fee too
