Not a problem at all.. as said above with the right attitude, and a quick, friendly, and GENUINE smile you'll woo your way into their hearts.
And CLEAN is of utmost importance... goatee, earrings, tats.. none of it matters ... but CLEAN appearance DOES !!!
A subltle suggestion.. lose the "loserboy"... and become what you truly aspire to be !!!
Wish you the BEST, my friend !
