Look, there's a fine line you dont cross with clients. Suggest this goes over it & could lose clients...people in upper management with well developed goodwill with regular clients might be able to pull it off (with some), but younger / newer employees trying this on clients they dont know or know well enough and maybe naively going a bit too far in the things they might come up with / nah, not a good idea. This is something that would require a policy set by individual cafe owners & managers. If they reckon its ok, then they take responsibility if it backfires not you. geez, does that mean I just agreed with someone elses opinion above? Woops, G.
