I once wore a pair of shoes that gave me blisters within minutes of walking. I had to buy a new pair of shoes and carry them around until I could change.
I tried a new skincare product that caused my skin to break out in rashes. I had to stop using it immediately and consult a dermatologist for treatment.
I got a botched haircut once where the stylist cut off way more than I asked for. I had to wait for my hair to grow back and style it differently in the meantime.
I tried a new diet that claimed to give instant results, but instead I just felt sick and weak. I had to go back to my regular eating habits and consult a nutritionist.
