All clients are a challenge, and some are plain impossible. However, I thank my stars there are some brands I don’t have to deal with. So until things get really difficult, or the wife gets a Harvey Nichols habit, here are a few brands that I hope I won’t ever have to work for.

1. The Liberal Democrats. For years you got through the day by playing devil's advocate, safe in the knowledge that you would never be in government. And then one day – you're in government. Suddenly that completely unrealistic portfolio of policies needs to add up. Tough gig I reckon.

2. Horse traders. The justification of selling a beef burger with horse meat in it is not an easy sell. Plenty of press clippings mind.

3. On-line gambling merchants. Even I have morals, and persuading people to bet cash they can’t afford to lose is just plain wrong. I feel the same about pay-day loan outfits. Until I need one that is.

4. The Potato Council. I'm just not sure what I could say!

5. Train operators. No matter how hard you try – you will never be loved.

However, if there are any champagne and fine-dining businesses looking for an enthusiastic champion out there, I’m their man!
