I'm pretty sure you won't be able to reduce the tip only increase it if you want.....I think the bar tipping is the same way. At first, when I got the email I was mad but I do always tip at least 20% anyway, more if the service is exceptional so it really doesn't affect me. If it reduces the hard sell of products I will be VERY happy with this change. I hated that more than the auto gratuity. I am guessing that there are people who did not tip or not tip very well and this will correct that. I do not know how much these people get paid but my guess is it is primarily the tips that pays their salary....so as long as the service doesn't suffer I guess I really don't have a problem with this. If the service becomes poor, well then I guess I take my business elsewhere. I won't get all worked up about it until I have my alone time in less than 2 months!
