Started my new job as cashier at gordmens it’s a retail store . It’s very difficult and still I’m struggling on the part we’re we do returns and price check hopefully I get it . one day is not enough time to learn everything. 😟😭 I also feel like the cashier that was helping me wasn’t going slow enough to see what I had todo . She was like this is difficult let me do it. Well explain it to me hello !!! I hope they don’t leave me alone on a cashier next time todo everything by my self . 😩
