After Claire and Tez's wedding, I wanted my photos back ASAP. Thinking Jessops in town would be open, we went down the day after to get them printed. They weren't open so we had to go to Morrisons.
I had two films and a load of digital photos to be printed. Apparently, they couldn't cope with doing so many prints in one hour, so I had to wait for two.
Two hours later, we picked them up and went off to Carol's parents to show them. Trouble was the all had a really bad green colour cast 
.
So I went back the next day. The sales assistant was not exaclty going out of her way to be helpful and took some persuading there was a green colour cast. She said that she could reprint the films but the digital pictures were right. That was until I showed her a print out from my PC on a laser printer which showed the correct colours! Two hours later, I came to pick them up. Before I had checked them, the assistant vanished round the back. When I checked all the prints, they still had a green colour cast!
I called the assistant back, told her the colour cast was still there and she took my print out and photos and stomped off to find her supervisor. When I'd explained everthing to the supervisor, she told me there was nothing wrong! After some discussion (!), where she told me there was nothing wrong with the prints, that I'd edited the pictures on the PC, as the background was grass on some of the pictures there was no colour cast etc. etc., she agreed that there was a problem! I finally got a full refund. This took over half an hour.
So I took them to Jessops and unsuprisingly they printed them correctly.
The moral? Only take films to be developed and printed to a company that knows what they are doing and not to places who try to make out that you are wrong and not them!
