Agree with mikey4444, Sunday deliveries were hard work, but given a trolley?
we would have considered that a luxury. We were given an extra wide bag for Sunday's and by the time I'd finished the shoulders were aching, they still do today, many years later. I did once ask if I could have two bags, to distribute the weight better but was told 'not to be so soft'. I couldn't really argue, the newsagent rose at four every morning, drove 26 miles,return journey, to collect the papers from the early train. He and his wife then made up the routes and we started deliveries at seven. Ah, the good old day's :o)
