Don Pablos penny pinching

What a rip off! My friend Jared was charged $1.50 for an additional side of guacamole today at Don Pablos. This wasn't a surprise at the end that got slapped on the bill, the waiter told him straight out what the cost was for more. Jared wanted more guac since he only got a small dab on his plate, and it was barely enough for him. It really should be no big deal for a restaurant to provide a little more so he can enjoy all the quesadillas he ordered. How is it any different than ketchup or pop refills? That is the type of thing that irks me to no end and makes me not want to return to a restaurant. Not a good way to make the customer happy now is it, Donny P?
