Touch screens for payment are increasing at convenience stores and restaurants. This new system is not too much trouble to me. But the situation is a bit different in the US. You have to choose how much you chip from a range presented on the screen, for instance 0 to 20 %. When the server watches, you feel pressured to choose higher value. Traditionally people did not chip at self-service shops like coffee and sandwich stands where they did not interact with a shop staff. But in the case of touch screen they feel guilty for not tipping. Touch screen system became popular during covid-19 pandemic. And the increase in tip revenue also encouraged the introduction of touch screen.
In the US service industry worker's income rely on chipping. But the increase in chip is not necessarily translated into workers' income. This issue of tipping in IT age will not be resolved, unless employees get stable income.
