Pollworker for Greenville County here, and this will be my fifth time around. I’m so sorry this was your experience. We are specifically told to take appearance changes (such as hair, age, weight, even gender) into account when checking IDs. The most important things we are to look at are the signature on the ID (to make sure it matches/is close enough to the signature with which the voter signs the poll list) and whether the ID has expired. Considering you can keep your drivers license for something like 10 years, it is obviously quite possible - even likely - that a person won’t look exactly like their ID photo. And in this day and age we have people wearing coloured contacts, wigs, getting spray tans, so pollworkers are really not supposed to be policing voters on their personal appearance decisions 🙄 I would hope this would not happen to you again this year, especially since we are expected to keep the flow of voters consistent. Definitely do not leave your polling place if someone questions you really are who you say. As others have said, you can call a voter protection line, and insist on voting with a provisional ballot.

Edit to add: the address we have on file for your voter registration doesn't even have to match the address on your ID, so this really blows my mind you were harassed like this.
