I talked to my sister recently. She told me a story which was shared below.
---------------------------------------------------------------------------------------------------------------
I bought 11 sausages(buy 10 get 1 free) and brought them back to the office.
Everytime when I encountered a co-worker then I gave him/her one whole sausage until there are no sausage left. One lady informed me that she never ate the whole sausage before, and she showed me her appreciation. Did the lady do not have money to buy herself a whole sausage? We all know the answer, since almost all mothers will not do that, instead they prefer to buy several sausages, slice them to many pieces then shared with the family.
