Yes, being in your face and assertive is important. Closed mouths DO NOT get fed lol If you want to be shy, this is NOT the job for you. Build rapport, you will be working with these people closely, shouldn't you take the time to know them and ask them questions pertaining to your shops?
I find I have the most success when I build rapport and then request several shops at once. I have gotten assigned 4, 5, 6, 8 shops at a time because I asked. If you want to be serious, you sorta have to be greedy lol
Helps prevent shop f*ck ups at least they give you a chance, know you BY name and know how reliable you are.
I email my schedulers alot (but not to the point of irritation) and because they know I'm actively looking for jobs and I've proven myself to their company, they are more likely to choose you. Also if your really detailed to the point of exhaustion it helps. Again I find mystery shopping companies, like opinionated people! You cannot sit on the 'fence', choose a side...lukewarm attitude is often a sign of indecisiveness. Even if the shop went terribly wrong, I tell the truth.
Since this one of my main jobs, I take it upon myself to do the best I can in the time period. I rarely do reimbursement shops unless it is from a PROVEN and RELIABLE company. I have been burned by sketchy companies. Unless it is a food shop or a return clothing shop. I do not even bother.
If you grocery shop a few times a week, I suggest Field agent (though I have mixed feelings) you can pick up a few picture shops for 3.50. I use it as something extra to do if in the area or close to my home. I never would drive out to get only 3.50? You probably spend more on gas sheesh.
