CHICAGO: Working the register at Dollop Coffee Co in the Loop one recent evening, Evelyn Rangel rang up a US$4.39 (RM18.14) almond croissant and stood by as her customer, having swiped her credit card, studied the tip screen that popped up.
Did the service merit a US$1 (RM4) tip? US$2 (RM8)? US$3 (RM12)? Those were the options prominently displayed across the top of the Square payment touchscreen. Below there were additional buttons that gave the option of leaving a custom tip or "no tip" at all before signing to complete the purchase.
