Be careful using self service weigh and pay machines. I weighed a packet on one machine and just checked it on the second to be sure - and it was about £2 cheaper on this machine !!! I informed the staff who told me I should inform the manager (who was sitting in the next seat) errr ok...so the manger was informed. I proceeded to weigh and paid for my packet at the counter.
The manager came out and checked the machines with my packet and when the second machine showed an even lower price than I had got originally she said this was due to a mistake she'd made just then on doing the process.
She went through the weigh and pay process again and this time the price came to the same as I'd paid a the counter.
The manager said the problem was due to the air conditioning unit above the machine but it weighs correctly- errr, not in my experience and why is the unit positioned there then if it inteferes with the operation?. She said the weigh machines are checked every day.
I pointed out the scale (now with nothing on it) was registering 0.00lkg she said its due to the , ''wind'' coming from the air conditioning and the machine does reset itself and sure enough it did. She went on to say it doesn't matter because ,'' its only 1.''
The weigh scale in a post office or any other service we pay for needs to be correct and an incorrect charge £2 may I imagine determine whether a parcel would actually get delivered or not.
I will keep double checking or just use the till (providing and hoping they're calibrated regularly) ????
