Shouldn’t be. Procedure generally is to get off the plane, walk to booth selling tourist cards, buy card, go through immigration, wait for luggage at carousel, get your luggage, go through customs, exit, find your transport to hotel (or where you are staying). Somewhere in that procedure, likely right after immigration, someone will collect the tourist card. The biggest issue is that there are two forms to fill out (one blue form for each person and one white form per family group).
