Lesson learned in my hustle is always be alert in everything cz you might be caught unawares. Customer anaweza kuja na Fake note na vile utakua in a hurry to serve him/her hapo ndio utakua umepatikana. Moreso never be too friendly to strangers to avoid Conmanship cz they come in a friendly way to get your attention and that's when u will b coned. Also do not do not leave un trained person at ua shop to avoid theft n people taking advantage of his/her weakness. #MeshChallenge
