This restaurant relies on its staff hustling for customers on the street.
Tips
register
Slightly negative — implies pushy or aggressive solicitation, not legitimate marketing. The most charged use is for sex-worker solicitation (e.g. 拉客女, lākènǚ); context decides which sense applies.
memory
拉 (lā, 'to pull') + 客 (kè, 'guest/customer') = 'pulling in customers' — the literal image of grabbing someone off the street.
