Hi, if you can fund these small purchases from your agreed expenses / budget there should be no problem. Some firms will agree a modest expense category for entertainment --- mine was £10 a month, ten years ago, but you can always divert a fiver here and there from housekeeping, haircuts and the like.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
