Sometimes they say "offer salt & bread" to present as welcome; there is also деловая колбаса - business sausage? - what do they mean exactly and can you say "предложить деловую колбасу" analog to "предложить хлеб и соль" on business occasions? (and as symbol for willingness for a good deal, because of the "offer" - предложение").
To explain the relationship of these terms, there is a phrase "all what is in the stove, on table swords" (I do not know the context why swords are important, maybe because of "who comes with a sword, will die from a sword") but if in ancient times they took bread out of the stove, nowadays you would take from refrigerator a sausage, probably for scientists the doctor sausage (докторская) and for business people the business one (деловая). The pejorative connotation with sausage is more clear on example of "sausage emigration".
