My card is good through May, so I will be using it my upcoming trip. However, I will not be renewing it. I am opposed strongly to the auto gratuity. This is not because I don't tip, but because a tip is optional and the amount tipped is up to the individual. This is nothing but an 18% added fee, just like the taxes.
It's true that you're now "saving the tip" or that you can have the tip adjusted if you feel the service didn't warrant it, but I just loath the concept of a mandatory tip.
Perhaps it's my concept of manners coming into play. I would never attend a wedding without a gift, but I hate when couples include mention of gifts in their invitations. The gift stops being a gesture of kindness and becomes nothing but a demanded fee for the privilege of attending their wedding. A little class, dignity and graciousness is all I ask. This rubs me exactly the same way.
