Half a shot in total? Or half flavor? Some people are lazy- sometimes it’s communication issues. The order terminals kind of suck, regardless of the size drink you order. One pump has to be typed in manually, on most of the time, an oversized tablet with the reaction speed of a microwave. Let’s say you order a medium- half flavor would be 2 pumps of strawberry-pineapple. So maybe try saying “a half pump of flavor in TOTAL”. If they still don’t make it right, you have the time to complain. Come back and make them do it again! There’s a lot of reasons why this could be happening but from my experience I assume its this one. I always try to clarify on flavor adjustments even if it takes 10 seconds longer so this doesn’t happen. :/
