The adoption of iPad POS systems is changing how restaurants interact with customers. A survey found that 86% of respondents prefer to input their own tip rather than have the server do it. Close proximity of servers encouraged 41% of respondents to tip more. Nearly 90% found iPad POS systems not difficult to tip on. Almost 30% would be more likely to tip if they had to select a "no tip" button. While most prefer inputting their own tip, 35% of women would tip more if the server input it. A majority prefer using iPad POS at casual or fast casual restaurants like Panera.
