It's had a slight impact on my income, as in previous years I always worked at things like open days, and this year they aren't happening in the same way. For in person open days they hired a lot of students for the whole day (so we got like 6-8 hours pay) but this year they're hiring many fewer students and mainly only hiring each person for a 30/60 minute slot. However the open days only happened a handful of times each year, so it's not like my income took a major hit.
I know some students who've been furloughed or had hours cut, but none of my friends who work retail/hospitality have lost their jobs. I'm sure lots of students have though. On the other hand, my uni's covid testing centre pays quite well so a few friends have got jobs there, and I know some med/nursing students are waiting to here back about vaccinator positions.
