I work for Tesco and the VAST majority of folk are fine – however there is one type of customer and we shall pigeonhole him.He is male(obviously),well educated,superior,smart,funny – and – well,once he hit his mid 50's a total arse!.Only a small proportion of blokes are like this but they seem to be at their worst with young lassies on checkouts – who by the way are probably going onto illustrious universitie careers themselves.So lighten up Mr crisis man,cos I'm scared I might turn into you whan I get to 55!!!!
