Moira and Bob are complimenting Mrs. Juniper on her coffee when they are interrupted by a loud noise. Mrs. Juniper says the coffee is so good because she has a new coffee grinder – the Whizzomatic, and it’s very good for business at the Wobbly Coffee Pot Café. Moira does not like the noise and says that the new grinder has to go. Mrs. Juniper refuses point blank. Later on, Bob and Mack are complaining that their stalls are very quiet.
