Aldi vs Audi

I now call the southeastern corner of England my home. Down here, they have a funny thing called 'l-vocalisation', which means that instead of the sound /l/, people are quite likely to produce a vowel (or sometimes it sounds like /w/). This is a widespread thing, people are familiar with it, it's not something that's really remarked upon. It does lead to some nice mix-ups though: someone recently said that he used to work for Audi. The person he was talking to said 'Audi, or Aldi?'. The two sound basically exactly the same.
