Bad gift certificate experience!. My son presented me with a $75 gift certificate to the White Dog Cafe. I took a friend to dinner and the bill came to $62. The management refused to give me $13 change, nor could the difference be applied to the gratuity! How outrageous is that? I wrote a letter of complaint. They very nicely called and sent me another gift certificate, this time for $50 (which I appreciated). However, it said "Does not include gratuity!" Moral of the story: never buy anyone a gift certificate from the White Dog Cafe! Very disappointing business practice.
