I remember trying to direct an Italian driver (towing) with two squabbling kids in the back, how to get to Carl-is-lee, I sent him on another circuit of Lancaster inner ring road. He had come off the M6 too soon, his map must have been out of date. And I was amused by his pronunciation and did not think fast enough. Sorry mateo.
Carlisle (car-liel).

I have heard Uttoxeter referred to as Uchester - being a Staffordshire man meself, but not from that end of the county.
Lilleshal - lillyshawl
Stroud (as in proud) in Gloucesterhsire (Glostersheer) and Stroud (Strood) in Kent (as in bent)
Shelsley Beauchamp (shellslee beechum)
Powick (po-ick)
Tewkesbury - (chooks-burree - emphasised as "chuck" if you are from Evesham (eevs-sham not evee-sham))
Tweeksburg as one American had it, but then it gives me permission to use that pronunciation regularly.
