Mrs Cooper said the time limit was too restrictive for her customers, who needed more than an hour for their appointments, and she believed two hours would be ideal.
She had run her business at the corner of Belvedere Rd and High St for the past three years and had raised her concerns with council after a similar round of parking fines about 18 months ago.
"The frustrating thing is that 90 per cent of my clients take longer than an hour and the tickets will be going to them. Also, my elderly clients can't be expected to park miles away in the rain. It just won't work."
Peter Morton, partner in Belvedere Rd accountancy firm Herbert Morton, said the hour limit was "crazy".
His clients needed more than an hour to conclude their business, he said.
Ms Thompson said numerous customers at Wild Oats also needed more than an hour to dine comfortably.
"A lot come to eat before heading up town to shop or look around. Sixty minutes is too tight, especially on a side street. It's working against the town," she said.
"It gives the overall impression that people aren't really welcome to stop and enjoy the town and what we've got, which is a shame."
Milan Hautler, Carterton District Council planning and regulatory manager, said the parking time limits had been in force since 2006 and "anyone can write to council" requesting an extension of limits.
