I've never thought about the sign for Macca's until now. (Thank you JClarke - you've got me calling McDonald's Macca's now, LOL)
So which sign is the 'official' sign for Macca's? The 'M' handshape or the Ronald McDonald one?
As for Starbucks, I've seen it done JClarke's way more often than I've seen the other way I described earlier in this thread. I'm not that great at describing signs.
