here's the way to ruin an otherwise good experience.
i chose casa sushi to cater my kid's birthday party. i ordered 4 different sushi 'boats'. plastic trays. the food was all fine. quite good in fact.
the problem came much later when while we were cleaning up from the party my wife told me how the delivery driver literally attempted to extort his tip.
the bill was just shy of $190. he refused to give change for the $200 my wife presented to him. first he didn't understand the language. then he stood fast arguing that she couldn't possibly want change. she had to demand the change. she was appalled by the driver's behavior.
sorry driving 4 blocks from your place of business and making one trip into a house at 4:30 in the afternoon does not qualify for an $11 tip. that kind of attitude qualifies for zero and had i been home that's what would have happened though my wife is far too easy and still gave the driver a substantial tip.
