Will frequent entry and exit from Thailand as a UK tourist using a visa waiver raise concerns with immigration?

Hi, I am flying from Siem Reap to Yangon (via Bangkok) in a couple of weeks time, and thinking of going through Bangkok immigration to put my drone in left luggage as there may be issues bringing it into Burma. 3 weeks later I fly from Yangon to Krabi (again via Bangkok) and will go through immigration in Bangkok again to collect it (although I’m not sure whether I’d go through immigration to get my connecting flight to Krabi anyway as it’s domestic?). I also was in Thailand for 3 weeks a couple of months ago. Is having so many entries/exits in my passport in a short space of time one or two of them for less than an hour) likely to cause me any issues? I’m a UK national and would be using the visa waiver. I’m worried the short entries might make them think I’m conducting business rather than a genuine tourist? Thanks!
