So, I gotta know...
They did that for me on my birthday. How is that an exciting thing? To have chocolate on a plate spelling out "happy whatever"? I was most UNDERwhelmed, but I see people who are excited about it. I could do the same thing at home. And at home I'd lick the plate* but I'm not going to do that at Palo.
To me, it felt like they were also supposed to give me something else, but they just forgot. I actually thought it was because my birthday wasn't noted and that was a last minute "oh let's do SOMETHING" sort of thing.
*actually I'd just put the chocolate in a spoon and eat it, forgetting the middle part of the process, but even doing that I'm still getting more than I am at Palo.
I'm often mystified, but this is up there at the top.
