I purchased a gig, nothing uncommon and the task seemed straight forward. I was given a quote for the job, I accepted. The seller did the gig and also went well above the request, almost 3x more work when it was done and delivered. I thought wow, that was a lot of work but I don’t need all of it. Then he came back to me and asked for a much larger tip to cover the cost of the extra work he did. I never agreed for the seller to do more and honestly I was happy with just the amount I needed for this project without the extra. I had already completed the order and left a review then he came back and asked.
What should I do? Should I give a tip comparable to the amount of extra work? Is it fair for a seller to do this to the buyer without asking first?
The quality was great and I would consider the service again but now reluctant to go with this seller if he does the same thing.
