Ikhlaq, 39, of New Street, Dudley, was found guilty of soliciting and fined £400 at Walsall Magistrates' Court.
He was also ordered to pay £665 in costs on Wednesday.
Ikhlaq was spotted by officers who saw the known sex worker in his Nissan Micra car in Wednesbury Road, Walsall, on 9 May.
PC Stacey Paterson, from Walsall police, said: "I've heard some excuses before but in the 10 years that I have been a police officer I have never heard a kerb crawler covering up his crimes by claiming to be buying tomatoes.
"Our officers and the courts saw through his lies and [Ikhlaq] has now been found guilty."
