Years ago, I went into a bakery to pick up a cake for my husband (then boyfriend). The girl behind the counter asked me if I wanted anything written on it, and I asked her to write "Happy Birthday Dan" on it. When she went to pipe the words, her tip was clogged.
What does she do... Turns the pastry bag around, sticks the tip in her mouth, and sucks out the clog!!! Then she starts to pipe on the cake!!!
I was in such shock that all I could say was, "um, I've changed my mind" and rushed out of there. Of course, I was young and timid then. Now, of course, I would give her a piece of my mind! That's one thing that never happens in my home kitchen!!!
