"I get this drink all the time at Peet's. It's much creamier there."
...Really? Are we at Peet's? They probably have different eggnog. There is literally nothing I can do about that. I'm quite sorry. What's that? You would still like me to remake it? You would like me to fill your THIRD venti cup with the last bits of this season's eggnog so that there will be less for everybody else? I'm pretty sure we'll have used a full carton on you alone. And how did you pay for your drink? Oh, with a free drink coupon. So we just threw away a carton of eggnog that could have been used on other customers who would have appreciated it. Not only would they have been appreciative, they'd have been ecstatic. People are crazy about eggnog lattes. So thank you for depriving them of that. Thank you for taking all of our eggnog without paying even though it's not as good as the eggnog at Peet's.
Really?
