No chips and bad attitude of manager!

I went to Ocean Basket waterfront, waited in line for a table, then waited to be helped only to then be told after approximately 20 minutes that the branch had no stock of chips. My family and I decided to leave and as we were exiting I asked a female manager to put a sign outside that they had no chips. I explained that I had my 5 month old baby, 6 year old son and it was not only a waste of time but and effort to only be told after being seated that they had no chips. She looked an me and grinned. It seems that it was amusing that customers were upset that they were put out in this way. They obviously don't value their customers. Ocean Basket Waterfront you need better management!
