You done talk am finish oga igbebotz, them get plenty merchants to trade with, to reduce stress of attending to too many customers for one merchant, I no see anything bad for person to decide say eh wan dey trade with one particular person, maybe due to trust or the reputation of the merchant or even em good rates and accuracy to dey make quick payment but then too much familiarity they cause problem for p2p market for instance a case where be say a particular merchant you done trade with for long go dey deduct money from your initial payment without permission due to too much familiarity, that's why I no dey like trade offline or even with one particular merchant to avoid that kind familiarity cause some merchant get that kind behavior even when you never familiarise with them talk more when you come do so.
