haifagirl, did you ever hear th expression – “The same service you give for selling a refrigerator you need to give when selling a microwave”. Meaning when you are in business, wheather its a large or small profit, if you are out to keep customer happy and you want them to come back – like this one surely is – you need to go the extra mile. Maybe this time they only came with 4 ppl. But if they were so happy maybe next time they will make their chanukah party here etc.
I am not pointing at this restaurant owner obviously, I am talking about the topic in general.
