Im not sure I would agree with the first two two analysis's of how this problem with streaks to the legs has occurred and agree fully with Tinxy
Why...well if it were due to perspiration there would need to be some serious perspiration to actually run down the leg and further more there would be other areas to the body where there would be problems such as under the arms
I somehow suspect that this is a very personal problem due to where the streaks are ...in short I feel she has had an accident soon afrer the tan application which has run down the leg and caused the streaks :o
This "personal" fluid is very good at stripping a tan
Asd you say it is such a shame when customers blame there therapist for problems which emanate from faults which they have effected and which are not within your control
HTH and don't let this incident get to you :hug:
