Aldi Maths

Aldi announced yesterday that they will be opening 500 stores in the next few years, creating 35,000 jobs. This represents an average of 70 jobs per store.  I have shopped at many Aldi stores around the country but never found one with a staff of 70: most appear to have more like seven staff. Presumably some additional staff will be required in the distribution channel but if Aldi need 35,000 additional staff to open 500 stores there is something seriously wrong with their business model. Furthermore, unless the store openings are accompanied by an upsurge in demand for groceries, the new customers must transfer their patronage from a competitor who will need to downsize to accommodate the reduction in sales. So how does Aldi arrive at this figure of 35,00 additional jobs?
